well good news, i seem to have fixed the coolant leak.

now back to the oil situation, are the C4's known for oil burning? i know cars burn a little here and there but i want to know how to find out where my oil is going to? i put the car on jack stands and checked all over i don't see a single oil leak from her she is clean as it gets...now that's got me worried what the issue can be. and the car isn't smoking it out the back as i had several friends "try" to keep up so they got a good look at my rear and say nothing comes out. i probably confused so many now with my msg but anyone got tips on where i should check?

thank you and sorry for the run on sentences, English isn't my strong side

Your owners manual has information on engine oil changing and selection. I use Mobil 1 because it is available and I think there are less deposits from the synthetic oil. The oil with the energy conserving or long life symbol are rated for use in a wide range of temperatures in the 10W-30. The other multi-grade oils require a higher viscosity for summer temperatures but should fit the temperature range for this time of year.

I use Mobil 1 10W-30 as well, here in the Carolinas.

I have onoly had 1 issue with unexpected oil loss on AAN engines, and that is the oil sending switch on the IM side of the block directly below the TB.

However if you are losing oil there, there should be plenty of evidence of that on that side of the engine, oil pan and bell pan.

Other than that my engine never consumed much oil. I run Mobil 1 15/50 but since I found out Mobile 1 is no longer truly synthetic I may be changing to a truly synthetic brand.
