quote odl21:

just about to change my oil and was going to use 15W/50 synthetic (mobil1) but given the cool temperate climate much of the year here in england i’m thinking maybe 10W/30 would be better.

i have a mildly tuned 302 with about 4000 miles on it and a slightly leaky remote oil filter adapter 🙂

what do the rest of you use?

thanks.

I have been using 15W40 but 10W40 would be better in the winter and just as thick in the summer. But my oil filter adapter also leaks!
