I've heard that 1 quart every 2500 miles is normal. I've searched and found that the brand and weight of oil could have a little affect. I put 10w40 synthetic blend in on the first time i changed the oil and then oil light came on after only about 800 miles. The oil light comes on when you're 2 quarts low right? so i searched and found that 10w30 mineral oil burns less quickly. Is this true and what else could cause the engine to burn oil this quickly. I had been driving it kinda hard, the first month of hearing a turbo can cause your foot to become lead. thanks.

 

I hear it was a quart every 1500 miles, but anyways. I would recommend not using synthetic, while its good for the turbo, it can also gum up the rotors. I use 20w-50 in my N/A and it runs beautifully. As for your other problem I have no idea, other than you could have a big leak?

 

check for leaks and I would avoid using 10w40 also

 

20W50 Castrol GTX is the perfect oil for a turbocharged rotary engine! Change every 2500 miles and call us if you're experiencing symptoms of headache, nausea or general low-compression.

20W50 Castrol GTX is available at finer Automotive stores everywhere. It is not likely that you will find such liquid at your local pharmacy, but it's worth a try.

 

thats to much oil to be gone. do you know where all of it is going ?? i dont think synthetic is a good choice by the way

 

my car dont use any oil between changes (about 2000-2500 miles) why is that??? it scares me sometimes...but i have no problems with it! hmmm

 

It's not the type of oil. Driving hard may result in using a quart every 800-1000 miles, not 2 quarts. Is your engine getting tired? Do you have any signs of oil (blue)smoke in your exhaust? I am going to assume you don't have any obvious oil leaks. Also, check you oil metering pump adjustment.
