Anyone try Castrol Startup with polarized molecules ?
The stuff is supposed to stick to your motor like a magnet after most of the oil drains to the pan during shut down. Most of the time I use plain ol' GTX 10W30. Just wondering if it'* worth the extra $$$.
If your that worried about cold start up Just go to a 5w-30 for winter. Additives are usually a gimik, your oil should allready do that. IMO I would leave it alone unless you get alot of noise off the valvetrain at cold start. (if you dont get alot of noise,your oil is doing its job)
