That simple eh?
So please tell us, how exactly does a turbo setup lead to a fuel dilution issue whereas direct doesn't.

 

Hi. Can you provide documentation or links to studies showing this to be the case? I've never seen any claim that you're stuck with whatever brand oil you first used. Especially since everybody's first oil is whatever Honda put in the car when it was new.

 

I think the best answer to this is the comment someone once made elsewhere:

"Relatively-high compression combined with low-tension piston rings seems almost a guarantee of fuel leaking down into the crankcase. This technology - along with tiny, turbocharged engines - which benefits the consumer with better fuel economy and higher power, seems mostly, though, intended to help manufacturers meet increasingly strict fuel economy standards, regardless of maintenance/repair issues down the road."

Honda now uses direct injection on a lot of engines including the Fit which has had it for 5 years. None of these engines have had fuel dilution problems except for a series of turbo equipped engines - high turbo pressure/ weak rings. If direct injection was really just the problem then wouldn't you be finding fuel dilution problems on all Honda cars equipped with direction injection?

 

So what was the cause of replacing high pressure fuel injectors on many Fits?

 

Strictly fuel injector failure. Totally separate problem. On the Civics and CRVs with oil dilution problems there were NO injectors replaced to solve their problem. Honda's solution to that problem was strictly a software update - no hardware replacements.

 

Any how about those owners who claim their motor oil "smells like gasoline" after a short oil change interval?

 

Ok, sorry about the tough question...here's one a little easier for you ...
Earlier you posted the following quote:
So regardless if the engine is turbo or naturally aspirated, is it safe to say that owners with direct injection can (and do) experience fuel dilution?

 

Some people say a bottle of bad wine smells like gasoline.

ALL cars can be said to experience oil dilution due to fuel getting past the rings since it's not a perfect seal, regardless of the fuel/injection system. In most cases it's a microscopic amount of fuel which affects nothing. In the case of the Civics/CRVs way too much fuel was getting past the rings and into the oil. When your oil level on the dipstick rises by half an inch to an inch you have a serious problem with gas getting into the oil. Honda telling the affected car owners that they need to change their oil more frequently to deal with the problem is Honda dumping the problem on the customer and walking away. If the customer has to do more frequent oil changes then Honda should be paying for that or providing a free service at the dealerships for the life of the car (in my opinion). Thankfully this is not a Fit problem - the current generation Fit does not have a dilution problem. We have a defective fuel injector problem primarily on 2015/6 Fits. The only solution is replacement.
