I use Mobil 1 15/50 in all of our Volvo's , Valvoline VR 1 racing oil {high in zinc}in our 1960 S2 Bentley.I am breaking in the new motor in my 1961 MK1 MG Midget on VR 1, will switch to Mobil 1 once it is broken in. My wife's 90 240 wagon now has 600K miles on it we have had it for 20 years always used Mobile 1. BTW how many mile on your car?
Would you recommend it in a warm climate like mines?
