Is dura-lube or slick-50 good to put in a 1.8t engine?

Question

VW GTI 1.8T

Answer 1

VW recommends synthetic oil for this engine. You have a five valve per cylinder and a turbocharger in a very sophisticated engine, don't experiment. Personally I would never use either in anything I own.
Edit: Consumers report did a test on these additives, they put them in a bunch of NY taxicabs, measured wear every 6000 miles. Conclusion, synthetic oil alone lowered engine wear, additives made no difference or increased engine wear.
SAE, paper on slick 50 argued that there is no evidence that Teflon in the product will form any kind of a film or even lay down flat against the metal surface, in fact that the teflon particles were more likely to remain perpendicular and increase engine wear.
Dura lube will make your oil more acidic, accelerating corrosion, etc, etc.

Answer 2

Slick 50 is just 50 weight oil and some graphite...it can plug your oil filter in really cold weather causing oil starvation or a burst filter....I would never recommend it. Duralube is a little better. I always recommend a product called Engine Oil Supplement or EOS which is available at GM dealers in the parts dept....much better product than other additives like STP or the two you quoted.
Usually, an oil supplement is not needed if regular oil changes are performed at 3000 mile intervals. Use a good quality oil like Quaker State and a VW filter...Fram filters are good too. Stick with manufacturer recommended oil weights like 5W-30 or 10W-30.

No. 1.8T is prone to sludge. any syntetic oil approved by vw has the vw sign on the back of he bottle. Not all syntetic oils have it, but if you don't do that and put in approved oils vw won't cover the sludge warranty. make sure you're oil filter is large capacity also because they changed the specs on that too. go to www.passatworld.com theres tone of info on the 1.8T engines there.

Oh my Gosh NO!

Expensive and does nothing for you at all! Stick with a mainstream Synthetic oil and change it at minimum twice a year, more often if you rack miles or race.

Answer 5

I believe that most people who really know tell you not to put things like that in your car unless it is having a problem, and then do it only on the advice of a "master mechanic."

Dura lube is very good I used it in a Honda
