im going to do my first oil change since i bought my car. i was wondering what is the best to use. i thought that someone said 20w50 but i could have been wrong. thanks for any input

 

I have always used GTX 10w-40

 

Castrol GTX 20W-50 or Mobile 1. Both are good oils that can be had at a reasonable price.

 

cool thanks for the input

 

20w50 Castrol GTX. I've read 10w40 is not the best.

 

yeah, generally you want to avoid 10W40 and 10W50 as the additive packages needed to get that viscosity out of a 10W base oil, tends to leave increased deposits on high reving motors.

Enough for some manufactures to try and void warrenties if 10W40 or 10W50 are used.

Castrol GTX 20W50 is what I recommend for starting and operating temps are above 30F and 10W30 GTX if temps are between 0F and 80F.
