I'm using about a half quart of oil every 500 miles

I still don't know why folks go to the dealer for maintenance. It's over-priced, it takes FOREVER, and there's no reason to believe it'll be done any better. I've been patronizing one particular quick-change business (NOT Jiffy Lube) for over twenty years. It's quicker, cheaper, and they use the same materials the dealer charges twice as much for.

BTW, Luke -- Mazda recommends 3,000 miles under real-world conditions. Page 8-11 in the manual. 2,500 miles is a bit too often, economics-wise. When I switch to Pennzoil Platinum at 9,000 (end of winter, probably), I may go to 5,000. I can't decide. The main reason to go synthetic is the heat tolerance.

On topic, I've NEVER had any reasonably new engine use ANY oil between changes. The people who say they should are just too lazy to find out why it happens.

Change intervals aside, I'm more worried about where a a liter of oil could disappear into so quickly. Should I ask them to inspect/replace the turbo? It did not use a single drop before this damned 5w20 change, now its drinking it liberally.

Update: Mazda service manager said that they put 5w20 on the statement even though they use different oils as required in vehicles. However they did start an oil consumption test starting with a fresh oil change this morning. I'm supposed to bring it back in 500 miles for an analysis.

I'm hoping its just a leaky cannister and not a borked turbo.

Either way, it's all under warrenty brotha. Drive that thing hard and make sure they see that it's burning oil.

LOL What a BS line. How hard is it to specify what was actually done to the vehicle on the invoice since that is your official record of maintenance?

Hope you were wearing your boots at the time. It was gettin' deep in there.
