I'm using the Lucas Oil variety because it's low-ash and smokeless. It's used in racing snowmobiles and the like.

Link: Lucas Oil 2-Cycle Oil

I did get away with using 50ml (less than 2oz) of this as a fuel additive. That's nearly 1:1000 ratio to fuel.

If that was the case then the 2T wouldn't work.

how about toyota/subaru changing the hpfp to fix this issue..?

As I mentioned, I only guessed at the 1:500 ratio. Don't forget it has other benefits if you intend keeping the car for a long time.
The Lucas oil sounds alright. Not sure what the air cooled spec means?

I couldn't find the Valvoline racing oil we have here but the outboard version sounds ok.
Premium base stocks are blended with a modern ashless detergent additive package to provide fortification for maximum performance in outboard engines.

like i mentioned cant royota/subaru just replace the hpfp?

That would prove expensive for all the vehicles shipped to the US by Toyota and Subaru.

My guess is that they are going to look for more of a precise, less costly fix first. I'm okay with that as long as it gets fixed.

Correct synthetic or snowmobile oil.

Otherwise just get the pre-mix oil that Rotory heads use

i think it should be really address now.. And they should act fast before they sell more of these cars with this problem.. im thinking toyota will find a solution and hopefully we can just get it fix as part of the warranty..

You can bet they are modifying the fuel systems for the future imports and will almost certainly be replacing the offending parts.
What else can they do?

I don't follow your logic on that one. 2T would act as fuel stabilizer because the oil won't allow the ethanol to attract water particles basically what SeaFoam does.

Thanks for the link. The Pettit stuff may be a better way to go since it's been proven in gasoline engines for quite some time.

I did the math and it looks like it'll only cost $0.65ish per fill-up if you purchase the 1 gallon container.

It's a hassle and I gotta believe the guys at Toyota are going to address this with a warranty recall but, in the mean time...

Hi TC,

You said "Something came to mind when ethanol popped up and maybe the HPFP is causing the ethanol to draw in moisture in to the HPFP as it compresses the fuel and washing the lubrication from the fueling system. It may mean the use of a fuel stabilizer to keep the moister down and all parts well lubricated. It will only get worse when they up the ethanol to 15%."

I pointed out the same process would then wash the extra 2T lubrication from the fuelling system as was the case with the lubrication in the fuel in the first place.
Unless the extra lubrication is enough to overwhelm that process?

That would be incorrect because the oils surround the ethanol molecules and prevent the ethanol the ability to attract H2O molecules. The oil in the fuel plus the 2T oil would lubricate the HPFP and stop the excess rubbing of the internal parts.
