Absolutely. It was a late night for me!

Rx super or rimular x the oil that protects of valvoline super diesel just depends on what I can get a good deal on I get a bit of a discount on oils but the margin is pretty thin

Just had a look on their site at their LubeDesk and i would be a little concerned at their recommendations.

They suggest a Dexron IID for the auto, when the minimum required is a Dexron III spec.

It also suggests a semi-syn oil for the crankcase in the V8, which some seem to think is a bad idea.

That said, I am sure if you get the right product, their oils are good !

everyone recommends a different oil (yes i have a few cars)

Now, I'll start off with "I've only skimmed that link" as I'm well aware of the good Doctors posts years ago on BITOG, but lets just say I take some of what he says with a grain of salt.

Some of his theories on viscosity, flow and wear needed some serious challenging, he was absolutely obsessed with running low visc oils, and his statement that F1 engines use straight SAE 5 oils is downright wrong, but for the most it's pretty right and a good read.
(I don't have a problem with ultra low viscosity oils in the right place, I was using 0W-5 engine oils in race engines in the early/mid nineties and I know, there's no such SAE grade but it was thin, it poured like water and the blender listed it as a 0W-5 ) but it's a really good read for those that have little/no knowledge of how the SAE viscosity grades work and their correlation to kinematic viscosities and temps.

Interesting on GW site... If you ask for Oil recommendation for TD5 you get "please phone 1800xxxxxx"
