370Z oil consumption

onzedge

So, I think that I may have an issue with oil consumption. At 12,400 miles now on the car, I am using about 1.25 to 1.50 quarts per 3,000 miles. I just started using the "measure the dipstick" method as specified in the TSB so I am not yet sure about my consumption against the chart in the TSB.

I am a bit concerned though about warranty. I have changed the oil 4 times so far -- the first change was performed at the dealer (at 2,000) and the other three by me. Nissan Ester was used the first two and Redline 5-30 the second two. Oh yes, I also change the filter at the same time as oil (K&N or PureOne). Is there going to be a problem, warranty-wise, because I performed my own oil changes?

I also have a GTM Motorsports 19 row oil cooler installed.

I appreciate your comments. Thanks and have a great day.

You don't have an oil consumption issue.

What leads you to this conclusion? I hope you are right.

Normal consumption of oil is considered to be up to a quart per 1000 miles. Anything more than that is probably considered excessive. Your answer will be found in a phone call to Nissan or your dealer. You're going to get all kinds of "opinions" in here. Mine is just one of them.

Since many cars can and do, I'd say a 1/2 to 1 quart at the most every 6000 miles is reasonable, which is about what mine does, anything more I would call "should be better". But, unless it gets progressivley worse, the best thing to do is just top it up. I ran a Camaro SS that drank a quart every 3k miles, for 120k miles. It never changed. It ran fabulous. But, when I bought it at 15k miles and ran dino oil, it used 3X more oil. I switched to M1 and oil use went down dramatically. I would say try different oils if you have a lot of oil use.

Unless you have an oil leak due to your cooler, Nissan shouldn't give you a hard time for doing your own oil changes or having the cooler. Neither would explain oil consumption in the absence of leaks. If Nissan did hassle you, I'd suggest you start moving up the chain and call Nissan North America.
