Why it's best: Pennzoil Platinum may not offer the absolute best performance, but for the money, it's hard to beat. This synthetic oil still performs very well and is much more affordable and easier to find than higher-end synthetics such as AMSOIL, making it the all-around best synthetic oil choice for most consumers....

Why it's a best pick: Widely considered to be the best synthetic oil money can buy, AMSOIL would be the #1 choice if it weren't for its high price tag (nearly double that of Pennzoil Platinum) and the fact that it's harder to find unless you're ordering online. AMSOIL synthetic oil can withstand extreme temperatures and holds up very well under extended drain intervals. If you want the best and don't mind paying for it, it's the way to go....

Why it's a best pick: Castrol's new Edge with SPT synthetic oil provides outstanding performance for the money. This particular oil is more than a simple renaming of Castrol's well-known Syntec - the formula has been tweaked to extract more performance, making this one of the best synthetic oils around today....

Why it's a best pick: Mobil 1 synthetic oil offers great performance and is readily available in retail stores and online, but typically costs a bit more than Pennzoil Platinum and doesn't offer much to justify the higher cost. Still, it's hard to go wrong with the oil chosen as the factory fill for all Porsche and Mercedes AMG vehicles, the Nissan GT-R, and many other high performance cars.... Read Full Review
This list has been unchanged for quite some time now, and the manufacturer's have updated/improved thier products. I suggest Bestcovery re-do their product analyses and provide a current list of recommended synthetic oils.
I am just a regular driver. I have had my Toyota GT 1995 for 19 years and 121,000 miles. I have used Ford motor co. oil, 10W30 synthetic blend and changed oil every 3K and the filter ever other time. It runs like a top and burns no oil. Walmart sells it about as cheap as you can buy. Why pay more.
I have used Mobil 1 or other fully synthetic oils in cars, trucks, and motorcycles since 1975. I change oil based on mileage and oil condition, not time. I have never had an oil related failure in an engine I have bought new or rebuilt.
OK, now all I hear is Amsoil! Once again I wonder if there are thoughts on Royal Purple? I think that this web site might just be hooked to Amsoil. Yep Royal is a few cents more, but running with some of my friends who race 25 and 500 miles or more, 97% run the Royal Purple. Wonder why?? In the NASCAR circle none use Amsoil. Wonder why?? Anyone?
egor, The reason people are talking about Amsoil is because they know its the best on the market. Amsoil beat out Royal Purple in all kinds of tests, and your wrong about nobody in NASCAR using Amsoil. AL Unser Racing uses Amsoil and is a personal friend of the founder of Amsoil. He said many cars may have other oils as sponsors but if you go in the garage the containers may say Penzoil or Shell or others but thats not what is in the bottles, its Amsoil. As Unser said," I'm paid to win races and I win with Amsoil" bottom line There are a number of them that use Amsoil. Can you go 25-35,000 miles on Royal Purple with out changing your oil? I do!
For the best synthetic oil and lubes look to Amsoil, it the best for the value. For a catalog just send me a e-mail at pebrown49n@gmail.com and I'll send you a copy of our e-catalog.
I have heard all the different oils spoken of but I have heard nothing of Royal Purple. I have used it for the past 10 years and all I can say is it WORKS! I have a Plymouth Voyager with 157,200 and it uses no oil and runs great. I have used it for the past 10 years and also in my Nissan Cube with 30,000 miles. Well speak up guys??
This analysis is bogus. The top Tier Mobil and Castrol products were not even tested.
Mobil 1 Extended Performance
Castrol Edge with Titanium Fluid Strength
And why would you ever choose a product as the Best based on price? Oil is cheap compared to an engine and engine performance.
We used to call Pennzoil, Pissoil, when I lived back in PA and no one in our mechanic group would use it, esp after Arnold Palmer (a real oil expert, for sure LOL!!!) started endorsing the stuff. Personally, I'll stick with the best, Mobil 1, and the company that started the synthetic oil business in the USA in the first place. Good old German technology came up with turning dinosaur oil into synthetic oil and EXXON/Mobil is continuing in that fine tradition. And, I'd like to know what experts "agree that the main benefit of using synthetic oil is the convenience of longer oil change intervals". If that is the main reson, you better look for smarter "expert", given that motors oils are relatively inexpensive. I think if honest research was done the main reason for using a synthetic is for the unrivaled protection against heat damage synthetic oils provide for an engine. I've used Mobil 1 in all my vehicles - foreign and domestic, since 1980 - so, I am expert enough. Mobil 1 is the BEST, else why would Corvette, Viper, BMW, ect., all ship with Mobil 1 in their crankcases? And, as far as pricing for Mobil 1, why would anyone shop at Amazon for motor oil? Walmart has excellent pricing for an excellent product. Way, way less than your near $50 price. SHEESH!
frisbee, yes Pennzoil is crap, but Mobil 1 is not the best oil on the market. Ask yourself why does a company sponsor another companies product? "FOR MONEY, THATS WHY" Mobil 1 is not the first to make synthetics, it was Amsoil, they have made it since 1972 and when they made the claim that they were" The First in Synthetics" nobody spoke up and said anything, if they did then Amsoil couldn't claim being the first. They had the chance to speak up and say no we were but Mobil never said anything. Mobil 1 is not out that many years, do your research and you'll find out. I spoke with the Shell Answer man and he said Amsoil was a great product and it was the best on the market, including anything they made at the time.
Jeff, you say Amsoil is hard to find unless you go online, we in a way thats true but its only because many parts stores don't carry it because not many people demand Amsoil from their parts stores and because of the price. Retail stores would rather carry a lower quality oil because of the price. If you figure in the drain intervals over the course of a year, it becomes cheaper than the lower priced oils. Most of your synthetic oils are about $ 7-9.00 a quart and they don't say anything about the extended drain either, if you want a cheaper oil you can buy the OE or the XL oils we sell which will cost about $6-7.00 per quart and you can still change your oil at between 3,000 and 10,000 miles respectively or you get the better oil and change it once a year or 25,000 miles. Check it out and do the math, you either change it 5 times a year or 1 time a year. My website is http://www.synthetic-oil-tech.com/1982486
I came across your article on "the Best Synthetic" motor oil. I am curious what areas did you base your findings on? It doesn't look like you mention detergent levels (Castrol is extremely low on these), or anti-wear levels (most "over the counter" brands removed or reduced significantly the vital zinc component from their oil two years ago), or even TBN levels (the element of the oil that is responsible for eliminating acids that break down oils that lead to sludge). I did see the interesting and dead on accurate information one person commented on the different types of synthetic base oil classification. But I also have not seen any mention of an API approved licensed oil. All engine manufacturers recommend an API approved licensed oil or it will void the warranty. The fact that you list AMSOIL number 2 on your list is alarming in the fact that most of their oils are not API licensed and therefore will void a warranty. If you are going to promote convenience that is one thing but if you are going to taut the BEST oil on the market I believe you have to take into account these other areas.
For the person looking for truly the BEST MOTOR OIL on the market I would encourage one to research Texas Refinery Corp's Pro Spec Synthetic Blend motor oils. They provide documentation on their API license on all of their oils as well as boast the industry’s highest TBN of 15+ on most of their oils. They even have oils that take protection a step further by incorporating "Moly" into many of their oils. Plus where you mentioned price earlier on AMSOIL they are more affordable.
I have been running this oil in my F-150 for 18,000 miles between drain intervals. And best of all they analyze the oil free of charge. I send in samples at 9,000 and 18,000 miles. I have a friend running this oil in his gravel trucks and is getting 50,000+ miles between changes. In my farm tractor I even run it as long as 1,000 hours.
Pro Spec offers the highest zinc and TBN on the market bar none. For the person truly interested in getting the most protection/performance for their buck I'd give TEXAS REFINERY CORP a call today!
I used Amsoil differential oil on the differential of my Benz. I probably had it ther for 2 years. Time came I had to replace my CV axle due to torn boot. I had a very hard time pulling the axle out when it should have slid out easily. I can't say that it was due to the oil but I have another similar car just dyno oil where I did this to and did not have such a problem.
David you are very wrong, because Amsoil is the first Synthetic oil to become licensed with API, and their oils are not a blend but 100% synthetic and they should be listed as the number one synthetic oil on the market, you want specs. on any of the oils I can give you msds sheets on any of them. Some oils do have a higher content of Zinc in them because the older engines on your classic and antique cars need the Zinc. You want info check out one of my website at http://www.synthetic-oil-tech.com/1982486 for more info
Amsoil is not the first in synthetic oils, it was the Germans in WWII, whom used the first synthetics in their tanks and vehicles. (FACT)
SS, could yu purchase that oil here during WWII, Amsoil came on the scene back in 1972 and put the claim out as the first in synthetics and not one company challenged them to the fact.Check out Amsoil Z-Rod oil with the Zinc in it your talking about. Many people have switched and won't go back to the others.
I agree with David, I have been using Amsoil for 10 years and I disagree that its the best synthetic oil. Due to the fact that it is not ESTER BASED OIL. READ THIS CAREFULLY AND YOU WILL FIND OUT FOR YOURSELF:http://www.carbibles.com/engineoil_bible.html
I agree with both David and RamairVGTO guy, due to the test Quaker State Ultimate Durability put out, Not 1 - I repeat not 1 stepped up to the plate, not Amsoil Not Mobil 1 and Castrol. Most Ester based oil is made much different then Polyalphaolifins based oils. Ester base oils are used in Jet engines and can tolerate higher stress and heat then Polyalphaolifins based oils (FACT). And with the Zinc, well even the old engines can use ester based oil without the zinc. I know I have a 7.43@183mph ProMod Mountain motor class drag car 67 Camaro that runs only on Redline oil and nothing else, no additives or anything but ester based oil on a Chevy all aluminum 650 cubic inch Big block that has computer controlled nitrous system on a 8-71 supercharger. Trust me not even the Amsoil oil could last on the runs we do at the track. So that said PLEASE TO ALL THAT READ THIS GO TO THIS WEBSITE AND GET A BETTER UNDERSTANDING OF ALL OILS REGARDLESS WHO MAKES IT: http://www.carbibles.com/engineoil_bible.html
SS, If you want a good racing oil the Amsoil Dominator Synthetic Racing Oil to provide superior protection and performance for high-RPM,high-temperature racing it comes in 15W-50, 10W-30,5W-20, or you can get the super heavy weight SAE 60 High-viscosity oil designed for high-horsepower engines. It resists thining effects of fuel dilution and provides exceptional wear protection. Give them a try, we have many racers that swear by the oil, NASCAR Bobby Unser uses Amsoil and highly reccomends it. Try the oil and see for yourself. Amsoil is the " First in Synthetics" since 1972. Briggs and Stratton has now teamed up with Amsoil to make a racing oil for their small engines, it will be sold through their dealers with the Amsoil name on it as they wanted it to be. Give Amsoil a try for your racing engine. You ever have a question we have a Automotive Engineer from Ford Motor Co. and hes a Lubrication Specialist as well on my team Check out http://www.synthetic-oil-tech.com/1982486

SS, if you didn't find Amsoil so good then why did you continue using it for 10 years then?
