MazdaSpeeds around this year are prone to gasket oil seepage on the exhaust side of the turbocharger. This cause unpleasant oil burning smell in cab and smoke from exhaust due to oil burning. This is especially evident during prolonged sessions of idling. Mazda knows about this problem and offered an extended service plan for 10 years/70,000 miles to replace the turbocharger and oil feed lines. The new oil feed lines reduce incoming oil pressure to fix this problem. I would highly recommend replacing these lines even in the turbocharger is fine. Another "solution" to this problem is replacing the banjo bolt to restrict oil flow and using thicker oil.

The Mazda Speed6 isn't really a sports car (RX7 or 8), but it isn't the Mazda 3 or standard Mazda 6. It has a turbo and was claimed to have great acceleration.. and it does, the oil just blows out of it. Mazda knows they had a problem with the turbo seal blowing so they extended the warranty on it to 70,000 miles I believe. Some second or third owners, as myself, had no idea. This car should not have this problem until well over 100,000 miles.

The only temporary fix I believe, now that I'm just over 70,000 miles is to change to a different turbo if I plan to drive this car with some acceleration faster than your typical 4 cylinder family car. Or drive like a 60 year-old and maybe I can just have the turbo taken off and re-sealed.. There are many great things about this car but buyer beware.. before you get 80,000 miles on this car, you may blow oil every 100 miles and have to spend over $2,000 to get it fixed and over a week in the shop waiting for parts. My mechanic said there are a few things to do so that the there is less engine pressure to the turbo, but for now I have to put 2 grand in a car that has 75,000 miles on it. Be careful!..

This car has some trouble handling hard hits from pot-holes in the road. Just go 0 to 60 very slowly and try not to get RPM's over 3,000 and it may last. My next car will be a Subaru!
