What kind of oil consumption are you experiencing?
Trying to get an idea of expected oil consumption. If you respond, could u
identify: 1. The oil u use 2. Mileage on your motor 3. How much oil in qt/1000mi. |

Re: What kind of oil consumption are u experiencing?
Dom, I didn't answer the survey because I didn't know how.
My 85,000 mile 90 with Amsoil in it seems to blow through the first quart very quickly. Within 1,000 miles, throttle dependent. Then oil consumption slows way down. Maybe a quart every couple thousand. If I leave it down a quart, it uses very little. |

Re: What kind of oil consumption are u experiencing?
Has anyone noticed a difference in oil consumption based on the oil they are using?
Steve, I have been busy datalogging and tuning the motor now that its back from Dr. Greekenstein addressing the piston ring etc. So I’m doing some things w the motor that u normally don’t in terms of rpm v mph profile just to get data for the fuel map. These motors like to chew up oil when u play around w them. |

Re: What kind of oil consumption are u experiencing?
I "voted" for 1qt/1000 miles, give or take, which includes both normal traffic hwy flow, and some spirited (3000 to 6000+rpm) driving. AT issue, as Steve points out, it seems the usage is greatest as level is at the FULL line on the dipstick. That is to say, that first 1/2 quart goes away way faster than the last half (to the FILL line). Bottom line: IT VARIES..
1990 5.7L almost 69k miles AMO 10W-40 (full synthetic w/ ZDDP concentrations appropriate for the LT5) Stock bottom end Ported except for the TB SW headers, 3" exhaust except for MF mufflers. |

2/3 of a quart just before the 3,000 miles oil and filter change. She has 83K. She sees the redline on every outing...[emoji1]

Re: What kind of oil consumption are u experiencing?
AMSOIL 10w-40 or 30, blended with Mobil 10w-30 high mileage
1990 #1727 performance rebuild 7000 miles, exhaust valve seals installed 1 quart of blend added every 2000 miles I agree the topped off oil consumes the quickest. I'll drain a few ounces from the catchcan every 500 miles which is more than others, but I like that the catchcan works effectively.1508681740033.jpg 1990 #1587 garage queen, doesn't get driven enough to analyze oil consumption.

Re: What kind of oil consumption are u experiencing?
I noticed the usage of the initial amount of oil as well. When I filed it up, and got on it, I could see a puff of blue. However, in subsequent romps on the throttle it certainly is not pronounced like that. The oil level drops but not in increments like the beginning. This motor, for whatever reason(Compression and valve sealing is good) has used oil before as in 1qt every 1000mi or so. More so if you have a day at the track.
