I USED to use regular ol in all my cars and do the LOF every 200 miles....untill my three year old motor rebuild scuffed the bearings on the 17 second car that I drag race...and only shift at 4600 rpm since the motor is stock and runs out of breath above that. I took the parts to a kowlegeable speed shop and was told that a lot of that is happening now since nearly all the oil companies no longer add zinc. He stated that a lot of guys are now having scuffed bearings and camshafts if they run slightly loose clearances. He recommends only Shell Rotella or name brand synthetics. The Shell stuff around here is only availabe as a 15-50 wt but he said it was okay to go with a 50/50 mix with another name brand oil. So I did that on the Horizon, but switched to Mobil one for all my other cars. The 96 1.0 Geo that I bought used about 1/8th of a qt in the first 2000 miles since I got it back in July so I switched it too to Mobile one.....in the last 4000 niles it has used about 1/4 qt...just like dino oil.

A HINT...do not buy synthetic blend oil since it could be as little as 1/5th synthetic. If go that route just buy a couple of sythetics and mix them with your dino.

I run a Wix or reguler Purolator.
