a lot of the advantage is lost yea, but i need my car to last until ive saved up enough for an engine conversion, so only the best will do
Daz if you want some of that Total i have used, i can get you some a lot cheaper than from the shops, but you might be very far away and postage might cost a bit, pm me an ill try an sort somethin out
the grade will be in the book, however mine states 15W-50, and this 5W-40 seems perfectly fine, in fact its better, esp on starts !.......flows a lot quicker with it being a 5W
when my car was made they didnt have the advanced oils they have today
