Fuel in oil

[Doc]

If you put in the correct oil amount 6.2 quarts which is 198.4 ounces. Another 5.6 ounces brings it up to the top hole! Just a good thing to know!!

Are you adding 5.6 ounces of oil ?

I'm trying it to see if it holds, it seems like when I put the 6.2 in it fills up the rest of the way to the hole with fuel which is 5.6 ounces. Don't know might just be a shot in the dark, but I feel like it's worth a try. Seems like it always stops at the hole.

I just saw Pennzoil has a new synthetic called Start & Stop technology it comes in 0/20 and 5/30, don't know what the difference is from the Platinum but maybe it could help or hold up a little better to fuel dilution!!!

Their brochure on this oil is pretty vague about everything, but it does specify that it provides protection against low-speed pre-ignition (LSPI). Since LSPI can be one of the consequences of fuel dilution, perhaps this is an indication that this oil is designed in part to hold up better to fuel dilution? Or perhaps their marketing department realized they could take the same oil they've already been selling and slap a different label on it?

EDIT to add:
Just found this, which says in part:
"The start-stop product isn't meant for the engine technology in newer models that cut off engines at stop lights. It's meant more for drivers in urban settings, traffic jams and similar conditions that put stress on engines.

“The issues of high temperatures, high load, the engine is running hotter," says Sean Nguyen, Shell passenger car motor oil scientist and technology trainer. "Those are the issues where we saw demand from the consumer side. And we focus on technology to support that and to protect not just the oil but the engine based on the extreme heat conditions that's being put on the oil.”

So Pennzoil's definition of Start-stop does not include our auto-start/stop, and instead of targeting the effects of fuel dilution, it seems to be formulated to hold up to excess heat. With our big oil coolers, I don't think that's the problem we need to worry about.

Looks like a misleading name they slapped on it then at least to anybody with a newer vehicle. When I saw it the first thing I thought about it was it was designed for the new stop start technology! THANKS FOR THE INFO!!!

My first oil report, just for reference, in case anyone wants something to compare to. This is one year in with just under 10K miles total and 44 hundred on this oil.

Metals are low, and that's good. Wear metals should be low on a 1,000-mile run since averages are
based on about 5,300 miles of oil use. In this case, we might've forgiven a little extra metal since this is only
the second oil change and usually, that means there's still some wear left over from the break-in process.
We didn't find anything like that though, and that's okay, too. The main thing to watch for this engine is fuel
dilution. The low flashpoint shows 2.8% dilution and that thinned the viscosity into the 0W/20 range. Watch
for a rising oil level next run.


Just got my sample results back from blackstone. Like the other poster I had 2.8 fuel dilution....

This oil change only had 1,000mi on it. I had dealer change it as I was concerned because dipstick smelled strongly of gas. He just looked at me funny and said he hadn't had any other complaints. When my truck was done (they collected the sample) and he gave me the sample I had him smell the sample and he said he didn't smell any fuel in it....I smelled it and it smelled like gas so either he lied to me or his smeller was broken.

I can tell already that I am going to get zero support from dealer!

Hey, loss of smell is one of the Covid symptoms. Maybe he needs to have his oil analysed.? In this case I bet his loss of smell is selective.

Well $hit...

Update: Checked my oil today, about 1,500 miles since I changed it. Smells like fuel at the dipstick again and the level went from just below top of hash to just below top hole.

Thought I was past it. I don't think it's worth stressing over but it's always gonna be in the back of my mind. /sigh

Just got my 1st oil change report from Blackstone, the fuel in oil number for the 7,000 mile oil change is 2.8%, which is .8% higher than their standard, but not too bad at this point in things. No antifreeze showing. A few numbers were higher than average, but that's to be expected for a 1st oil change with new gaskets, seals & a new motor just running in now. All in all, it's doing well.

Just got a reply back from Mobil 1 on fuel dilution. Here is their reply!

I have been thinking that short trips where the engine doesn't stay up to temperature for very long might be a contributing factor in fuel in the oil. Looks like Mobile confirms this.

Here's an update for everyone. As I stated earlier, after getting the injectors replaced, there was a slow rise in the oil level, but it never quite got to the top fill hole. It stabilized there for a while, so I quit paying such close attention for a while. I've checked a few times recently, and amazingly the oil level has actually come back down to where I filled it! (And no leaks of course) I suppose initially a little more fuel got into the oil, nothing to worry about though, then the rate of fuel dilution later was exceeded by the evaporation of fuel through the crankcase ventilation system. So the oil level went back down.

To make a long story short, if you are having a problem with oil level climbing excessively on the dipstick, get your injectors replaced! I wouldn't be worried if you are just one of the people with 2% dilution on a Blackstone oil report though. This is a DI Turbo engine, a little fuel dilution is bound to happen, especially with short trips or city driving. No one should accept oil that is climbing several inches above the high point on the dipstick, though.

Really glad to hear, Wade. You certainly had more than your share of angst with the problem.

Someone should do a video on how to replace the fuel injectors. I would do it myself if I could follow a video so I wouldn’t need to worry about this issue long term.
