I'm going to change oil tomorrow, oil, filter, and oilsensor
It's a TDi engine from.. 1995? has done about, well no one really know, my guess is 200+ km..
Would it be a good idea to run some engine cleaner through it? anyone with good or bad experience, using engine cleaners?
some people say the engine cleaners can clog the turbo. i've done one before without any ill effects. just follow the instructions. the fact that it thins the oil out means not putting any real load on the motor while cleaning it out.
Right before I change oil I will put some ATF in. The detergents in it will clean out the engine pretty good. I use 1/2 qt in a 5 qt engine. drive around for for a bit. I don't put a load on the motor like jtanguay said.
