MoTox8410 Posted June 10, 2005 Report Posted June 10, 2005 is there any negative effects of running thicker oil besides slightly worse gas mileage??? i think the o-ring might slightly be leaking so what are the benifits of runing thicker oil and what are the negative effects??? Quote
93CutlassSupreme Posted June 11, 2005 Report Posted June 11, 2005 thicker oil gives higher oil pressure, but more start-up wear an oil leak will continue to leak no matter what kind or grade of oil you run Quote
1990lumina Posted June 11, 2005 Report Posted June 11, 2005 an oil leak will continue to leak no matter what kind or grade of oil you run Correct. Although higher oil may seem to help the problem, it won't solve it, and eventually will start to leak again. Quote
MoTox8410 Posted June 11, 2005 Author Report Posted June 11, 2005 right...i dont plan it as a permanet fix but if i helps slightly ill do it..... do you think that 15w50 woukd be way to thick er what would be practical to run Quote
JoroCorona Posted June 12, 2005 Report Posted June 12, 2005 Too thick in my opinion. The car was designed for a 5w30. The highest I would run is 10w40. Quote
gp90se Posted June 13, 2005 Report Posted June 13, 2005 I ran 20w50 in my 3.1 for a week because the o-ring let go, and I didnt feel like changing it. When you start the car, let it warm up for ~3 minutes (till the temp gauge starts moving) to limit any engine wear. Quote
MoTox8410 Posted June 13, 2005 Author Report Posted June 13, 2005 whats the problem with the oil system in the 3.4??? Quote
digitaloutsider Posted June 13, 2005 Report Posted June 13, 2005 Who said there was any? The only problems they have is the same shitty O-ring that the other 60* V6's got. Quote
MoTox8410 Posted June 13, 2005 Author Report Posted June 13, 2005 ohh...i thought there was something wrong with it as far at oil pressure...idk Quote
