"I dare say somebody will come along later to tell me how wrong I am"

Not at all, I`m in the same camp as you Paul.

We had a guy in the other day with a 97 Impreza(140K on clock) who insisted we used 10/50 as he found the engine would run a couple of degrees cooler So off he went to halfords to pay £50 for a gallon. Its all down to marketing a product.


We have three barrels of oil, Std 15/40, Semi synt 10/40 and Zetec 5/30. That lot will cover over 95% of motors that come through our place.

Only a PD or the 3.0 Isuzu`s will get any different for now.
