Oil consumption

[Jdhart1312]

I have a 2016 Tech Pack GT350. Just bought it at 49k miles, and it has 53,4XX miles on it now. I was told no oil consumption when I bought it, but have started to notice that may not be the truth…

I changed my oil when I got it home at 52k miles with Amsoil Full Synthetic 5w-50. The vehicle seemed to have drank a little bit of oil but nothing terrible. Was a long road trip so I thought nothing about it. After changing the oil, 800 miles later it seemed to be at the bottom of the dipstick. I ended up changing the clutch at 52,900 miles on the car (aftermarket clutch about blew up my transmission. Pilot bearing was gone and plates were warped from bad install). After changing the clutch out, I didn’t pass 4k rpm for 500 miles and did no WOT pulls. Oil level seemed to stay the same. Once I fully broke in the clutch, I started having fun again going to 8k and having fun with the car. Went to check the oil 15 minutes after driving the car and the oil level dropped beneath the bottom dot on the dipstick.

Is it possible that it consumes only under WOT and spirited driving? Seems to have stayed the same under cruising and low rpm, but when I started having fun it seemed to drink some oil.

I’m just worried because I’ve only got a third party warranty on the vehicle that the bank sold me when buying the car. It offers a new motor if something is wrong with it, but it’s still a third party warranty so I’m iffy about it.

DISCLAIMER: All WOT pulls were after the engine oil temp was above 190 degrees. The car didn’t pass 3k rpm until it was at 190 degrees.

I can tell you how my 2017 is (and I think its similar to 2016):

- 70k miles on my car
- If I drive it only on highway, say very long road trips, it consumes very little (1 qt every 4,000 miles).
- If I drive in city a lot, with some spirited driving (once in a while 5-7k), which in my case this is 95% of my driving, I have to add 1 qt every 1250-1500 miles.
- If I drive very aggressively, repeated 8250 rpm runs, it consumes 1 qt every 1000 miles.

In my opinion, car consumes oil under 2 scenarios:

- While its cold, during cold start, the longer it takes time to bring cylinder head temps, the more it consumes.
- Doing engine braking, crank case vacuum is the largest culprit of the rest of the oil consumption. So if you are doing a lot of rev matching and even briefly doing engine braking at high rpm, it will consume a lot of oil.
