2000 Toyota Camry 4 cyl Two Wheel Drive Automatic 235000 miles
My Camry is now " using" 1.5 qts between oil changes, which I consider excessive for a 4 qt capacity. I've always changed my oil every 3000-3500 miles since new, initially using Castrol Syntech Blend 10W30 and then Castrol's High Mileage 10W30 for the past 100k miles. This car does not drip oil on the driveway, nor does it smoke out the tail pipe. However, for the past couple of years I have noticed a burnt oil smell coming from the engine compartment and I did recently have the valve cover gasket replaced to stop a leak. My question is whether my car is burning oil via leaking rings or whether it is leaking oil from other seals and is just being cooked on the engine somewhere. I have tracked every single gallon of gas that I've put in this car since it was new (8,045 gallons of Chevron regular) and my gas mileage has been consistant at around 29 mpg for the past 7 years. In fact, it has recently climbed to 29.11, so would this increasing mileage be possible if my rings were wearing more? Should I be concerned about losing 1.5 qts between changes? Should I have a compression check done? I know this is anal, but it's been bugging me. Thanks
P.S. - I left a $5 donation.
