If you were putting it in a lawnmower engine sure go with the WalMart stuff, but for $6 why would you switch from a proven oil in a $20,000 engine? Doubt you can even get Hitech oil put in your car if you have it changed at WalMart.
No, I really do not know, but for 6 more dollars every 15,000 miles I'm not going to find out. I do know from a friend that rebuilds truck engines with a million+ miles that the cleanest engines are those running Dello 400 and those with a slight buildup on them are using Rotella T. The ones runing anything else have losts of buildup/sludge on the inside.


This post is my opinion (free advice). It is not intended to influence anyone's judgment nor do I advocate anyone do what I propose.

I'll try to find the link to an article that was based on a report from a retired chemical engineer that evaluated the additive package of various oils and Supertech had a better additive package than Shell Rotella. One of the best was Valvoline Premium Blue that is recommended by Cummins.

thanks very much.That is one great informative report for sure
I learned a lot about oils I never knew
Interesting as it shows Chevron Delo 400 as one of the best
not to be confused with "Delo 400 LE" rated one of the worst
but are for PRE 2007 engines according to the Delo website

toughnut, obviously most people don't "really know". They just see the brand name and are drawn in by it thinking "why" on the price difference.

Supertech oil has to meet all the standards and qualifications that any other oil does. It is very renowned and I have yet to meet one single person who has every "damaged" anything with their oil. I've heard it is packaged by Mobil oil.


4 whopping cylinders on Toyota RV's. Talk about great getting good MPG. Also I have a very light foot on the pedal. I followed some MPG advice on Livingpress.com and I now get 22 MPG! Not bad for a home on wheels.

http://www.turbodieselregister.com/TDR57_Oil.pdf. A excellent article and it does not show Walmart's Supertech oil as being a great oil. And if the OP wants to know more about motor oil, I suggest some reading on the forums at www.bobistheoilguy.com. You will find actual analysis of both unused oils and used oils there and info on what additives are in various oils and why they are important to your engine,

I believe it is packaged by Warren Performance Products, thus the WPP on the bottom.

well I have to say every one raves about Rotella T and yet the wallmart Supertech scores higher so that says a lot right there

Yeah, but...
It is WALMART oil, specially made and packaged for sale in the dreaded WALMART stores...
It HAS to be terrible stuff!
Doesn't it?
