Thread: Oil Weight for Summer?

pepboys and autozone sell german casrtol 10w30. which is ore like 10w40

is the rotella synthetic? and is it good. ive been using pp for a while and i kinda wanted to stick with it but the thickest they offer in platinum or ultra is 10w30? would that make a difference in my oil pressure if im using 5w30 now? or should i try to get 10w40? it gets hot here in fl

went ahead and just got back from walmart (1am) lol came back with some rotella synthetic. 1st time using this stuff. Read good things about it. Got the navy blue jug in 5w40. It says its comparable to conventional 15w50 on the back so im sure my oil pressure will look better aswell as the summer around the corner. Cant wait to start it tommorrow. Its to late and loud too now. lol

alot of people rave abouty the rotella being one of the best oils out there over the counter
