Possible crickets fix? Adding a capfull of synthetic 2 stroke oil per tank full?
 

When I had my BMW 135i, I read about the HPFP failures and recalls. Mine was replaced under warranty.

In reading about that fuel pump, someone suggested adding a cap full of synthetic 2-stroke oil to each tank full of gas, saying this would help make the fuel pump last.

I've asked about adding the capfull of 2-stroke oil on a couple "crickets" threads here, but no one has tried it that I know of.

My car I've heard the crickets once, but otherwise I don't hear the crickets, or i'd try this trick on my own car to see.

I'd be willing to be that this gets rid of the crickets, and if not, there's no harm in trying.

I've been putting 2T oil in my tank for the past 3 weeks. I'm happy to say I'm chirp free.

Did you have crickets before adding the oil to your tank?

I'm interested to see if this actually reduces or eliminates the crickets.

Yes. It was annoyingly loud.

Does it matter what kind/brand is used?

I was told to use either low ash or no ash 2T oil. Other than that, it shouldn't matter. I put it in my tank at a 1:1000 ratio.

What, just short of two cap-fulls? I suck at math, BTW.

How come no one uses Lucas oil ? Isn't that made to clean and lubricate the fuel system ?

Dunno, give it a try. Fuel with ethanol is considered to be a "dry" fuel (from what I've read) and lacks lubricity. I can't understand how a mere 10% could cause HPFP lube-related noise. I think it's the water content that causes the chirps.

It's 50ml on the 1st fill up. After that, it's based on how much fuel you actually put in the tank. I used an oral syringe I got from CVS to ensure accuracy. As for the oil, I used Lucas Oil semi-synthetic 2T with low ash from Pep Boys. It was $3.99 for a small bottle, which is enough for 4 fill ups.

I personally wouldn't do it if my crickets returned. I'm wary about fuel additives, 2 stroke oil generally goes through carburetors or simple fuel injectors for stuff like dirtbikes, lawnmowers, pumps, etc. I don't trust it going through the high pressure system in a modern transportation vehicle, I'm not entirely sure it won't wear something or gum up the system. The stuff is designed to be burned so I doubt it will have a significant adverse effect on the valves or cylinders but afterwards I worry about the oil fouling the catalytic converters, interacting poorly. Two stroke oil is not designed to be sent through a catalytic converter and the catalytic converter is not designed to filter burning oil (at least not in significant amounts, like consistent 2 stroke oil use over the lifetime of the vehicle). Ashless oil is supposed to be safe but I haven't seen any source I trust or even a consistent source other than word of mouth.

I'm sure that there is a 95% chance that nothing bad will happen, that 5% scares me though and I don't personally think it's worth it. Just the other side of the coin for everyone talking it up.

Don't worry about it.

People have been using it for over a year to cure crickets.

Any negative effect you think it may have won't affect you as you will sell the car in 6 years.

It's like using crappy gasoline. It will take years for sludge to build up and cause a problem.

I though the same thing. Only used 91 octane in Nebraska, with no ethanol. First time I had to use 10%, I had crickets. Loud ass crickets.

At the ratio we are using, I doubt there will be any long term issues. Plus, during the winter, I doubt 2T will be needed.

I am going to see if this helps: http://mystarbrite.com/startron/

I put it in my motorcycles, for other reasons.

Hence my 95% statement, personal statistic I pulled out of my ass, I would not be surprised if a car goes 300k miles with no fuel issues with 2 stroke oil in every tank.

Could you elaborate about it "not being needed in the winter"?

For me, the chirps were at their worst on hot days. Since it is colder in the winter, the chirps shouldn't be much of an issue. That has been my observation.

Funny, the first time I noticed my car was completely silent it was 110+ outside and I had just gotten done driving through the foothills in a spirited manner. I got the car in January, car got quieter as the months got warmer.

:iono:

I have yet to see anything definitive, but even at it's loudest the noise was just an annoyance, wasn't going to do anything about it until confirmed failures were reported, so far none yet.

The chirp is just an annoyance. One that I got rid of. I have even gone down to a 1:1200 ratio on the 2T and I'm still chirp free.

Would adding this result in warranty denial?

After the pump issues, I can't imagine them having the stones to do so. On the other hand.... I'd be more worried about it gumming up something else. Found this while googlin' around:

Klotz Uplon Fuel Lube provides upper cylinder and fuel pump lubrication. Protects the induction and fuel delivery systems from dry, abrasive properties of methanol alcohol. Uplon Fuel Lube increases horsepower by reducing power robbing friction. Seal conditioners maintain constant fuel pressure and prevent lean-out conditions. Blends with gasoline, methanol alcohol and nitromethane.

I would love for my cars exhaust to smell like BeNol.

The would be awesome.

Yeah that phrase makes my bullshit meter go off.

Company seems a bit off their rockers, but hey whatever helps you sleep at night.

Sounds like snake oil to me, I wouldn't expect more HP but if it fixes the crickets and it's safe to burn, more power to you. Either way, I'd rather deal with the crickets and wait for a fix than putting an unknown into my fuel system that's just going to cost money. Especially something that should be covered by the warranty when there's eventually a fix.

I've been running this stuff for a while now. Lucas 2 stroke low ash. Using 1-2oz in a full tank. It's night and day between a tank with it and a tank without.

Don't care about the HP claims. And there does seem to be a new fuel pump on the way. When it does arrive, I'm going to wait and see.

It might be snake oil, but if you looked at today's gasoline, especially California's gas, I'd call the gasoline snake oil before i called anything from Klotz snake oil.

Klotz, as far as I know, is one of THE best oil companies. I may be wrong, but I remember when mixing my own Nitro fuels for models, Klotz was the very best oil to add.

Today's gas formulations are just stupid, mixed more for emissions than performance, and the addition of ethanol just adds more problems into the mix.

A capfull of 2-stroke oil per tankfull will do absolutely nothing negative.

Oh you'll get no argument from me on that. Ethanol subsidies are profoundly stupid.

I've been using the two-stroke watercraft oil for 5-6 months. For me it doesn't fix the crickets. They kind of come and go now, after my replacement fuel pump.
