Which motoroil do you use? brand? miner. / syntet? visko?
I use Valvoline turbo V mineral 20w50 in summer and 10w40 in winter.:lala:

 

My Z gets Amsoil 10W-30 synthetic on the street Amsoil 20W-50 on the track.

My '02 Chevy truck gets Amsoil 5W-30 year round.

Hastings filters for both.

 

Amsoil 5-30 in the GTA, 4th gen TA, and beretta. whatever's on sale for the cavalier.

 

00 Silverado & 87 Z-28 both get Mobil 1 & AC Delco filters.

 

Mobil 1 Supersyn 5W-30 with Purolator PureONE Micronic filter. I'm probably going to try 10W-30 next time.

 

Last 10 years Mobil 1 5w-50 synthetic

 

Last 13 years Mobil 1 5w-30 synthetic, summer and winter. Just switched to Mobil 1 oil filters. Last 13 years have also been using magnets on the filter and in the oil pan. They catch a lot of microscopic metal particles. I'll always use them.

 

Castroil(sp?) 10w-40 and AC Delco filter

 

Aimsoil 10w-30 in all three of my trucks and my wife's Monty SS. I use the mobil 1 oil filter

 

Mobil 1 15w50 w/ AC delco ultragaurd upf25 oil filter in the Formula.....castrol w/ac filter in the 84 (when i was driving it),and whatever for my 99 crapalier w/ac filter

 

Quaker State 10W30 has always been in my car. Ever since day one. Then I switched to k&n oil filter. Runs fine with this combo.
