Hey guys,

I was wondering, what type of oil works best in these cars?....I have a 03 TB LT 4x4......Im also a 3,000-5,000 mile guy as far as changing the oil goes.....Thanks

Btw I just bought it used with 30,000 miles on it.....thanks

Mobile one 5w30 full synthetic will keep you out of any trouble. I have used it since I bought my 2002 new. 7 qts makes it a little pricey but it is a good oil! I go 5 or 6 months or 5,000 miles. I think with the 7 qt capacity the engine is much easier on the oil than lets say my high output turbo saab which is very hard on oil and prone to sludge if you don't use full synthetic and change every 3,000. The TB's 4.2 is a very well designed engine.

I put standard Penzoil 5w30 and change it every 5,000 miles.
