i tryed the search button but i couldnt find anything that answerd my question, and that post didnt realy help, all it said was that it should be long life all the time, which is fine, but im not paying 50 quid for the stuff, when i can get normal oil from halfords or whereever for alot cheeper, and so long as its changed regualy and kept topped up does the same job, so is it ment to be 5w-40 or 5w-30??
thanks
tom
