Ive been reading the boards for hours tonight, and ive still got some quesions.
1. In the Chat Room hosted by this site a few days ago, 15w-40 was suggested to me for my 6.6L Trans Am. 67k Miles, and it doesnt burn oil to my knowledge. This is a Summer Only car. The plan was to use this oil with an AC delco filter, and change it every spring.
a . I would like an Unbiased opinion on why Delvac 1300S is better than Delo 400. Or Vice Versa. I dont want to hear about any other oils besides those 2 please
2. At 5k miles, Im plannin on switching my dads 4.0L V6 '034Runner to Synthetic. It calls for 5w-30 year round.
a . Would using Delvac1 5w-40 be a bad Idea, since its against Warranty?
b .How long could I go per change with said 5w40 oil, with Toyota oil filter.
c . If I use 5w30 TriSynthetic, how long should I go per oil change using Toyota Oil Filter.
