ok, i usually use SAE 10w-40 in my 96 GT, but i was just wondering something here, thinking about the usefullness of windage trays and such.......would switching to a 10w-30 give me less windage on the crank? just a random question

 

I would comsider going to 5W30 if I were you,perhaps a Mobil 1 or something comparable.The windage doesn't change w/ weight and or viscosity but what deos change drastically is friction,both in the oiling system and the crank rotation.

5w30 on a 70k mile 96 GT............would that reduce friction?

 

I will be at 0w-30 with my 100000+mile short block castrol syntec makes this german oil that is greenish in color that is a very good oil to use. I had a friend that had some sheets saying how good some oils are to others and this one came up as number 1.You have to think when your car is cold your oil is thicker.You start your car and a thick oil will be more harmful then a thin oil. Now most of you will say what about when your car gets hot? Will the oil break down faster? nope thats the reason for the syntec technology. They have found something that will not break down their oil at high temp's and also last longer going to every crack and groove.but thats my 2 cents

ps: I have used amsoil for a while and I love it. But my friend had this castrol oil and i feel in love, so its all up to you.

 

?

 

i like royal purple.and i've seen drag cars run like only 2 or 3 quarts of oil.

 

i see where your going with this, but i cant risk harming the engine

 

never use under the quarts recomended

 

I use 20w50 in the Escort. It doesn't have very many miles on the new motor, but I rev the hell out of it's leaky ass exhaust all the time just to piss people off with their loud stereos sitting next to me
