And he said with the gauge being digital, it doesn't "catch up" to the true reading. Which I can understand but whatever. Data logs will show the true readings. I really do wish these gauges could be displayed as a number, that would be a bit more helpful.

They ran a diag and everything came back ok but that doesn't mean something physically could be wrong. It's documented and I'm not planning on modding the car so it'll all be covered under warranty for a while.

He said the oil level was ok. But the dip stick does make a difference on how it can read. Go to a 92 Camaro, pull out the dip stick and see what I'm referring to. You can make that dip stick not grab the residual fluid on the side. Where as this wire dip stick will always touch the side, causing the oil to cover it. It's not a stiff piece of wire, it will bend.

I guess I'll keep an eye on this and see how things go down the road...thanks for the help and I'll bring up anything that happens down the road.

Something like that?

Yes. Mine did and still does that. I haven't had any issues with it other than it shooting up like that whenever I notice.

I do track my car from time to time and do some spirited driving every so often

I can't say that you don't have an issue but I do have a warranty to back it up incase it were to go bad.

I would agree with the other posters. Any question of how much oil is in the engine...CHANGE IT.


Start all over change it and count out how much goes in. Check the stick right there cold, hot after running 20 mins etc until you and the dealership are sure where the level is and its correct.


You talking to someone that put and xtra quart in his Jeep not looking at the gallon jugs correctly after changing my own oil five times before.


On my LT4 I check it cold in my garage and hot after running so I get an idea what the stick its telling me. And I agree its not the clearest dip stick in the world.
