Hey guys,

This is my first turbocharged car and I'm just wondering if you guys have noticed that your oil is black before the recommended time or km's to change the oil. It is a new car so I'm wondering if this is a problem or if it is common on turbocharged cars. I changed my oil roughly 3000 kms ago and now my oil looks like a dark coffee color

 

This is normal for cars that are tuned rich the best thing you could do for it is get your car tuned.

 

it is normal for turbocharged cars. I noticed some improvement after using the extended performance mobil 1 synthetic which can be used up to 15K ON N/A cars.

 

Smell it make sure it does not smell burned. Also make sure is not too runny, hard to tell with Mobil1 since is so thing(being synthetic). If it does not smell burned and it feels like is somewhat still OIL, is probably fine.

I recomend switching to a better oil, my personal recomendation is AMSOIL. But there are others which many people swear by, like Royal Purple, Eneos and Rotella.

 

Yeah, I've noticed it too. I think it is more the running rich issue than just having a turbo. I noticed it smells like unburned gas... Guess I needs a tune

 

Just remember, tune = no engine warranty if you take it in with the tune still on the ECU.

And my oil, after 3k hard miles is a light brown. The engine's not burned any oil either (w00t!).

 

Synthetic oil will turn dark before conventional too.

 

untunned evos run pig rich from factory, means some of that fuel will be pushed down the crank case and get your oil dirty.

 

FYI, we carry many great products, easy as spray into yor throttle body and or induced thrue a vacume line, and also premium pour in the tank, that will maintain your top end clean free of carbon deposites, you can visit our thread https://www.evolutionm.net/forums/sh...ighlight=wynns


any tech questions pleas dont hesitate to ask.

 

My oil in my 03 is 100X's cleaner now between changes with 100k+ miles than it was with 10k miles. Definately due to how rich the fuel maps are from the factory

 

Yeah, like wat the guys say, the 'rich' part could be a contributor.

My car's at 6500km & I have done 4 oil changes, includes fully syn, semi syn & even motul 300V, all w-40 oils. Even barely 1700km interval, I get coffee from the oil sump I don't drive hard.. alot of cruising though at about 90-100kmph.

Looking forward to a tune when error codes & rev limits are supported in the flash.

 

just get your car tune right and will see a big different on the oil color..................

 

You think thats bad, our mazda's have the direct injection and combined with the pig rich stock tune the oils shot at like 1k. We're at ~2.5k changes now because the fuel dilution gets so bad
