Breaking in a VW TDI engine

[Moretalk]

I know this is a truck forum but I have a question about breaking in a diesel TDI engine. Jay wrote a great article about breaking in diesel truck engines. I was wondering if the same applies to diesel engines for sedans/wagons? From what I've seen, there's a lot of good info on this site.

Any help will be appreciated.

Tell us about your TDI. Is it new or rebuilt? There are a lot of guys on here who own a TDI and are very knowledgable on the subject.

I broke mine in according to my manual. Back in 2002 and my 2003, it was no cruise use for the first tank (or 500 miles). The only suggestion I have is to drop the factory oil before the first recommended oil change. I was surprised at the amount of filings in the.

Thanks guys for your responses. Below is a message I left on another site but didn't get any help - just answers like "Don't try and reinvent the wheel". Actually, I was asking because I didn't know. I should have posted on this site but I found you guys later. Thanks again.

I have broken in approx eight new gasoline engines and have used 5W-30 mineral oil for 10K before switching to synthetic. I also changed the oil and oil filter the first time at 100 miles after loading the engine fairly heavily to seat the rings. I changed the oil and filter every 300 miles for the next 1200 miles and saw metal particles in the oil at each change.

I believe it is essential to seat the rings in a diesel engine to prevent blow by which dilutes the engine oil with diesel and prevents one getting the best out of the diesel engine.

I have also read that the turbo needs synthetic oil as mineral oil will not afford the necessary cooling and will gum up. However, if synthetic oil is used from day one - how will the various parts of the engine seat? I know that various manufacturers use synthetic oil as factory fills.

My son-in-law in England has a 1.9 Passat 130 BHP TDI, lots of torque and great fuel economy. At last we have clean diesels here in the States and I am looking forward to getting my first one.

I think because the new VW engine has a high torque peak it will probably be almost as fast as the I-5 powered Jettas. And I guess everyone likes the prospect of 40 mpg or more in freeway driving too.
