Gas in the Oil

+1. get it out of there NOW ...

Gasoline is NOT a lubricant. Because it's there, your oil is really thin and way below the HTHS value needed for good bearing protection ...

It's almost a bomb waiting to go off. Change the oil and the PCV valve today and check the injectors for leak down overnight.

This is one time the BITOG mantra of an early change being "cheap insurance" is probably worth heeding

Am I wrong?


I don't think that's bad advice from Renault, but it sounds to me like they're not confident that they fixed the injector problem with the software update.

I'd agree with that. There are lots of reasons to not idle, particularly excessively. But, what comes down to basically an outright prohibition on idling when cold sounds like covering for a flaw.

Maybe now we see another rationale for start/stop nonsense.

The estimated volume is between 0.5 and 1.0 quart in 4.6 quarts = approx. 11-21%.


Then I think you're assuming more risk than needed.

5 quarts ELF Evolution 900 SXR 5W-40 has ordered - to be changed ASAP!

First of all, I'd get the oil sooner rather than later.

Second, I'm having a hard time even picturing how that much gas even ends up in the oil.

Most of my "shade tree" work is with older British engines, and specifically MGs. Not too long ago, I helped a friend with an MGB in pretty sorry shape. When he brought it to me, it was barely running. The carburetor was set very rich, had a leaky fuel diaphragm(not uncommon on this model carb), and the auto choke circuit was not completely disengaging when the engine was warm. The engine showed low compression and about 30% leakdown across all four cylinders which(aside from a leaky #3 exhaust valve-not surprising on an engine in this condition) we traced almost exclusively to bad piston rings. Although it was a "perfect storm" for fuel dilution, there was not an overly strong gasoline odor in the oil when we drained it.

BTW, my friend considered that lump enough of a write-off that he just left it in the corner of my garage when we changed it. I'm going to autopsy it one of these days and may rebuild it if the block is solid and the crank didn't suffer too much damage. Otherwise, I'll split the scrap price of a few hundred pounds of cast iron with my friend.

Thx for sharing this story, bunnspecial.

Trade it for a Fiat 500 POP.

No comment: oil out after 2600 miles (factory fill + 10-20% gasoline) and in.

... and thanks a lot for the correct advises saved my wife's loved car!
