On which Dex 3. All dexron oil is supposed to match a certain grade. 3 in this case, so all Dexron 3 should be the same. However I can't bring my self to use that coma shite in my car.
Fuchs Titan range for Dex 3 is usually generally recomended on oof. Cirtainly was recomended to me anyway.
Trouble is coma is freely available, and Fuchs is very difficult to find locally IME.
Why do you call it so? All Dex 3 should match a specification provided by GM. Is it just a brand image thing?
Unless you can prove Comma is poor in performance or gives trouble in use, it like saying I cant bring myself to use the ASDA paracetamol. I only use Anadin/other branded paracetamol. In the latter case at least the only difference being more revenue to the Anadin manufacturer and no real performance benefit.
Once again D your picking an argument on something we actually agree on. Read it as you like, but I agree fully with what your saying in principle.
However, its my car, and i will install whatever product is I see fit.

Hopefully between us we will help the op to make his own mind up, and he can install as he sees fit.
As said, again, all Dexron 3 should meet the exact same spec. You could argue that the cheaper stuff is inferior or fairly priced, or you could argue that the expensive stuff is over priced or somehow better quality...
Personally, for the sake of a few quid, like tyres, I'd rather play safe. But that's MY choice.
