Hi all
I have just sorted out a leaking dry sump pan on my VX engine, now comes the question, what oil to use, to re fill it.
Previous owner recommended 5w50 oil, the engine is producing 250 bhp, with a dry sump,does it need to be a 5w 50 grade or could I use Mobil 1 0w 40 for example, I read some where that going over 40 grade can have other negative effects, to counter balance the ability to take high revs.
There seems to be very little difference in price, but I have used Mobil 1 in a lot of other cars and its easier to get hold .
What are the pros and cons ????
