Oil which addresses the deposit associated with Direct Injection engines?
« on: March 19, 2009, 09:28:12 am »
There is a current thread here

http://www.bobistheoilguy.com/forums/ubbthreads.php?ubb=showflat&Number=1407413&fpart=1

which discusses deposits which seem to arise in DI engines even with the use of synthetic oil. And Havoline V 5W30 is being promoted by Chevron as an oil to combat such deposits.

That was synthetic oil as well in the article. I wonder if it does the same with Dino Oil?

I wonder why DI engines should cause anything special in the way of deposits on intake valves.  Why?   there is no fuel on the manifold side of the valves and the combustion chamber side should be just like any other combustion chamber.

Weird.   My engine is DI so I guess I'll find out sooner or later.
