RE: Facts about oil sludge
ORIGINAL: Cruiserhead
My car runs cool at speed, it's stop-n-go heavy traffic and heat soak that heats it up. Maybe longer running breaks away particles but it doesn't heat up for me.
I've seen several 150K+ 1.8t's that are fine. Read about more that are fine. Honestly, I don't agree that it will happen to every 1.8t. I haven't seen it in my personal experience on high mileage 1.8s.
Sludge may or may not happen but your statements are unclear and contradictory.
following your theory, wouldn't seafoam just break loose alot of crap to get caught up and clog vital lines? I like your preventative maintence ideas but the doom n gloom is [:'(]
When you go on long trips the engine gets a lot hotter and breaks away the built up garbage from the pick up tube and gets clogged.
Sludge really won't develop in the engine un-less you use regular oil and change it irregularlly or every engine for that matter.
ALL of you that ownes a A4 1.8T is gonna get sludge no matter how good and how often you change your oil at some point.

RE: Facts about oil sludge
So wait a minute. Are you saying that even with using synthetic oil and changing the oil every 4k miles, sludge is going to happen? Are you serious? That sounds like grounds for a recall. On the other hand, if you're suggesting that sludge will happen if you use conventional oil or if you fail to keep up with your oil changes, I'm apt to believe that.

There isn't a recall per say for it but there is a world wide TSB for it. If a 1.8T engine developes sludge and the customer can show proof of all services performed (at least every 10k) up to the current mileage the repair is free of charge by audi regardless of mileage. They will first check the bearing wear on the cams and if its ok there is a lengthy 9 hour repair to the engine. If the bearing wear is too severe you get a brand new engine courtesy of AUDI. Look at AMZE's thread about my car is broken, he got a free engine.
So keeping records of your oil changes is a must.

RE: Facts about oil sludge
I was talking to the mechanic that did the state inspection on my car. He said that using synth oil loosens things and would not be good to use. Also said the OEM was conventional oil....
My thought AUDI races, racers only use synth oil therefore Audi + Racing = use synth oil. Does that make sense?
What are your thoughts?
