Was looking in Walmart and saw this oil. It's cheaper than the Castrol full synthetic I usually get. Has any one used it? Is it any good?

I bought my first jug the other day, but have not opened it. I was a Mobil 1 "snob" for many years, but with all of the certified testing done by SAE and API, I am certain it is good quality oil.Other than anecdotal evidence, I don't think ANYONE can truly PROVE that one brand of oil is really "better" than another assuming they are test to the same standards.

Stay way from Castrol Syntech.It formed a hard red varnish in my high performance hot engines.Castrol sued Mobil ! and won entitling them to label their highr refined Castrol Syntech as Full Synthetic oil. So Mobil ! and all the rest went that route.Some Mobil1 Euro spec oils are now real Ester based synthetics.Someone else here, posted a reply a few years ago with info of who was selling full synthetic here in the US Redline is one. there is a difference a in the early commercials in the seventies when the real ester based synthetics came out. You cn't hold the blade of a screwdriver dipped in it between finger and thumb. I hd to replace the gaskets in my Plymouth when I first used it. Ol was so slick and thin and it shrunk some of the gaskets designed to swell in the presence of dino oil.Service Tech at Mercedes says my Mobil 1 oil they install is now the real deal.Porsche and some Honda engines use their propritary real synthetic oils and ATF.On edit Mobil sued Castrol not the other way aroundSecond Eruo Spec is determinedby Scientists and in the US "Synthetic" and in the US by Business Men and the Court.

Google, 'Who makes Walmart Super Tech Synthetic Oil', or something similar.You'll get lots of reading.

Then it was Citgo. they too did not have any equipment to manufacturer true Ester real synthetic oil.Real synthetics look for Euro Spec real synthetic oils.For a time mobile One had on the rear of their bottles "100& synthetic oil except for the base carrier oil." or some such and on the front 100% True Synthetic.Royal Purple and Red Line. Amsoil just buys their "synthetic oil" from whoever and repackges it. They do sell a Euro Spec Synthetic now.

Is it any good?Well, It's not an RV but, I've used it now for about 4-5 years in my '08 Honda GL 1800 Goldwing. The bike has ran just fine with it, no issues, no weirdness anywhere. When I dump it at each oil change, it looks like used oil, just like any other oil. The bike gets the same fuel mileage, it starts the same in cold or warm weather, just like it did with other brands of oil that I've used over the years. So, take this with a grain of salt here, for whatever it's worth. Scott

Every owner's manual states what type of oil should be used based on viscosity, synthetic or non-synthetic, SAE, API, ILSAC, ATSM , etc ratings on the bottle. I don't know of any that specify what BRAND of oil to use. It just must meet the manufacturer's specs.
As long as you use an oil that meets the manufacturer's specs, I really don't see any difference in oil brands, except with price.

I used Walmart Super Tech in my 460 Bounder for over 80,000 miles. Replaced engine with a stroker. The old engine still looked almost new inside. No wear on cam and lifters. 0.0015" taper on #1 cylinder wall. At 140,000 miles, it used a ½ quart of oil in 5,000 miles.

Actually they are a blender, as many are. They buy their base stocks and additives from various suppliers. Very common practice with many "manufacturers".

From their web site;

If all AMSOIL motor oils were API licensed, the company could not source new raw materials from multiple suppliers, which would greatly increase the threat of supply disruption and the likelihood of extraordinarily high prices. To solve this problem, the API must establish base stock interchange guidelines for synthetic base stocks just as they have for other base stocks, as well as develop interchange guidelines for other components too. Furthermore, licensing formulas limits the ability to quickly adopt new technologies as they are discovered; each variation from the originally licensed formula requires re-submission for complete engine testing (see the Ask AMSOIL entry above for more information).

As to the OPs original question, while not the synthetic, I use their dino oil in my gas farm tractors, and have for years. It seems to be working as well as any other oil I've ever used.

Well Mobile 1, and Amsoil last I knew were TRUE lab created synthetics.

Most other "Synthitics" are really very highly refined Dino Oil (Source Shell Rotella Presentation at an FMCA rally)

Odds are the Wal*mart store label brand is really a well known brand re-labeled.

After I first replied I started looking on the Internet for more information about real Synthetics, currently, and dino based so called Synthetics which are just more refined dino oil.
I looked at a number of sites and did not bookmark them.
Amsoil of course does not refine or manufacture its oil products according to the two or three sites I looked at.
This is a general discussion and I just repeated what I read. I've not been able to post links here so I didn't even think about it.
I spent about half an hour at one time and mybe that long the second time.
My second search term was who makes Euro Spec oil in the US which is where I found the info or the third which was who sells Euro Spec oil in the US where I found three or four US labels selling Euro Spec rel synthetic oil and that Amazon carried some brands.

Euro Spec vs US dino base.
52.72for 2x5 qt jugs is 5.20 a qt.
I paid over 10.00 qt for Mobil1 10w40 us spec at Wal Mart here.

I use it on all 4 or my vehicles, all with over 150K miles and no issues. Sent a oil sample in from the Duramax at 125K and it came back that I still had 75% of the oil life remaining after 10,000 miles. I also use the Fram filters designed for Synthetic oil from Walmart.

Yes I have been using it for the last 80k miles and 12 years. It keeps the engine much cleaner than the regular oil I previously used.
