What oil do you recommend for my 914 daily driver? I use Castrol GTX 10/40 but have seen some posts that you shouldn't use any multi-viscosity oil less than 20/50 because of lower oil pressure at idle that may cause a flickering oil pressure light. I've also heard some people who use straight 40 weight or even straight 50 weight oil. What weight and brand is best for good oil pressure?

I've also heard some people who use straight 40 weight or even straight 50 weight oil. What weight and brand is best for good oil pressure? I use Castrol GTX 20/50. I've been told that lighter oil will leak more (it's thinner, so it comes out easier). This was recommended to me by a friend who's owned 914's for over 20 years. This is from the Valvoline website: The "w" in motor oil stands for winter. The first number in the oil classification refers to a cold weather viscosity. The lower this number is, the less viscous your oil will be at low temperatures. For example, a 5W- motor oil will flow better at lower temperatures than a 15W- motor oil. The higher number, following the “w” refers to hot weather viscosity, or how fluid your oil is at hot temperatures. The higher the number, the thicker the oil at a specified temperature. There's a blog about oil that discusses the zinc in oil issue. He states that it's a myth and that what matters is another performance standard. If you can find it, it's fascinating reading. It's also VERY long. I think its called rat540 or something. I think there is a thread or 2 on here about it. You'll probably get a whole buncha people chiming in, so strap yourself in! |
