I need to do a quicky oil change in the MG. I'll be doing some engine work in September, so will be draining again then and consequently want to put the cheapest stuff that will actually be safe in there.
With temperatures as hot as they are now, and as hot as they usually stay through September in Kentucky, I'm thinking about dumping in SAE 30 or SAE40 rather than the normal 20W-50.
Any thoughts on doing that? Of course, I can just toss Supertech 20W-50 in it, but if a straight weight will give me as good if not better protection in 80º+ ambient temperatures, I'll do it.
