Oil Weight
Anybody know why my oil cap says 5W20 oil, and the manual says 5W30? Seems 20 is a bit thin with high ambient temps.

Thanks for the replies. I'm wondering if they switched to 20w because of the valve train ticking problems.

I have a question regaurding oil weights as well. I had my oil changed yesterday, and I accidently grabbed Castrol Syntec 5w-50 instead of 5w-30. By the time this was realized the oil had already been put in, and since its like 5 bucks a quart I just left it. Will this be ok? Should I take it back and have it changed again to 5w-30? Thanks in advance...

Dang. I ran a couple grand with Mobil 1 50w. Should have RTFM first :-)
At least the ticking went away. ------------------ 2K GT Stock FoolRichard |

"I have a question regaurding oil weights as well.

Now that we are in to spring, I wouldn't think it would be a problem for you. Then again, I'm the dummy that used 50w on the 2000 GT when 20w was spec'd. ------------------ 2K GT Stock FoolRichard |

Here's my logic...
I live in a place that rarely hits freezing in the winter and usually hits over 110 in the summer (sometimes as high as 120). I run with Synthetic Mobil 1 15W50. I figure with the high heat in this town and all the areas around it, the 50W portion of it should hold up better.

I'm assuming very few of you have actually seen the inside of a mod motor but the oil passages are very small. Than is why the manual recommends a low weight oil (5w20 or 5w30) depending on model year. My car says 5w30. When you use a higher weight oil 40w or 50w the oil does not pass through the motor as quickly and may not lubricate properly. You may not see any problems for years but I wouldn't try it.
Just something to think about. FWIW I use 0w30. ------------------ 00 GT, MAC Offroad H, Steeda Pulleys & Timing Adjuster, 4.10’s, Flows w/turndowns, UPR shifter, UPR Pro Series LCA’s, Lakewood 70/30’s & 50/50’s, Weld Pro Stars, Kaenen Cobra R Hood, 253.8 RWHP/292.8RWTQ 12.91@101.93 (1.74 60ft) M/M 100, 7085 Recent Pic from Moroso |
