Oil consumption

Flstfboy1 · 12-27-2018, 12:43 PM

Been driveing my 6 speed 2018 zl1 for about 5000 miles and have been noticing that it burns a lot of oil I have had an oil change but before the change I added about 6 quarts over the 5000 mile run.anyone else notice heavy oil consumption with there car ,the dealer said that is normal with a vehicle driven above 3000 rpm, I'm not beating the car but I do like to drive it at times . any response is helpful thanks

Well the dealer can say thats normal but I would be very upset with any engine that burned oil at the rate of 1000 miles or less per quart. If it was my vehicle I'd go to a different dealer and insist on a diagnostic check of the engine.
For reference my LT1 (not a boosted engine like yours I know) burns no oil between changes and I shift above 3K rpm a lot.

Good luck!

Here's a thread asking about oil usage for reference. It shouldn't use that much oil IMO.

collinms · 12-27-2018, 01:26 PM

It's going to depend on how you drive it. Higher rpm and engine braking will increase the amount. All my previous GM cars did the same. The LSA in my V would drink about twice as much as the Lt4 in my car. Anything over 1 quart in 1k miles seems like it might have a problem. Just my opinion though, I'm not a mechanic or engineer.

Flstfboy1 · 12-27-2018, 01:38 PM

I did make a call to Chevy, I am waiting on a call back told them I was unhappy with the dealers response, I just never heard of that much oil consumption with a new sports car with no mods made to it thanks again

6qts over 5000 miles is a ton! Unless you track/drive the hell out of it I see no reason why it would be that high. I’ve put 7K miles on mine and not had to add oil in between changes.

Scraps0f · 12-27-2018, 02:17 PM

When I put my car away with approximately 5k on it, lots of spirited city and suburban driving, plenty of stop and go driving, lots of high rpms, and a trip from NY to the tail of the dragon. I had only notice between a half to a whole quart difference when measured. A couple of hash Mark's on the oil stick below max when I checked that before changing. I would be very upset with that dealership if they told me 60% oil consumption was normal between fill ups.

SJFGTO · 12-27-2018, 03:29 PM

As stated 6 quarts in 5000 miles is not the norm for this engine, even with a fair amount of spirited street driving.

Absolutely unacceptable oil consumption. I put 4000 miles on my car this year, with 2 track days, and it didn't burn a drop.

6 quarts between fill ups?

harner · 12-27-2018, 04:18 PM

I'd continue hammering on GM about this consumption issue. At least you brought it to the dealership and opened a case so they didn't label it as neglect.

I had a dealer do that to me on a performance vehicle long ago and didn't have receipts to verify I changed oil regularly. Now I am beyond anal with keeping track of oil changes.

Good luck.

A friends car was doing the same thing. Dealer changed oil had him come back every 1000 miles after putting 2 quarts in over less than 3000 miles. They we authorized to rebuild the motor. Only thing I was surprised by is they rebuilt the motor vs putting a new short block in. Oh well car is fixed now.

Stephen12ZL1 · 12-27-2018, 05:12 PM

run that thing harder...the rings need to be seated. I'm not kidding. "Putt around" LT4s seem to use more oil than expected. Sign up for a track day and give that car what it deserves.

SteveV · 12-27-2018, 05:19 PM

Wow, I have changed my oil 3 times in the 6300 miles I have put on her: 600, 1500, then at 6000. Between 0 and 600, she burned no oil. Between 600 and 1500, I put half a quart in her. Between 1500 and 6000, she used a quart.

So, in 6300 miles, I have added 1.5 quarts of oil in between oil changes.

I am no expert mechanic; but if I had put in 6 additional quarts in that same time period, I would be VERY worried about my motor.
