Over 4,000 miles so far.

I didn't check the manufacturing date, although it is a 10th anniversary edition which should mean it is fairly recent, correct?

If you have to "check for the noise" you likely don't have the issue. The crickets chirping is loud enough to hear while sitting in the car with the engine running. Sounds like a super bad belt tensioner.

A normally operating HPFP makes all kinds clicking and clacking, but that is perfectly normal.

It is the same part number, but the updated parts have a green dot sticker next to the part number. The updated parts have been produced since April of this year.

@Terrapin77 and @sierra, would you mind giving me input on this? You both seem to advocate this Lucas Oil 2T.

Another poster recommended this Mercury Quicksilver 2-stroke oil:

A salient feature about it is compliance with TC-W3:

Lucas also makes a TC-W3 oil:

So given all of the above, would you still say the Lucas Semi Synthetic 2-CYCLE Oil is the best choice for our cars? I just don't know enough about the science of it.

By "checked for it" I mean I turned off the radio and sat in the car for a few seconds before shutting it off. I could hear it just fine with the windows up and the radio off.
Back when I was a production line mechanic if I heard that sound I would have been walking the line trying to locate the bearing that was getting ready to fail so I could have the replacement part handy for the next scheduled shutdown or when it failed, whichever came first. I don't like that sound and yes I know in this case it probably has nothing to do with a part about to fail. I still don't like it.

I decided to use the 2T method after reading sierra's posts on the subject. I don't have a recommendation on what 2T oil to use. It just happens that the oil I mentioned is the only 2T oil the Pep Boys by me sells. All I know is I have been chirp free since I began using it. Sierra does say to use a low ash or no ash 2T oil.

I haven't been keeping up with this thread lately, but I figure I should share that I now have a little over 7,000 miles on my FRS and no longer hear the chirping. Never had the high pressure fuel pump or anything replaced. And I use regular 93 octane fuel, no E0 fuel or anything.

I have googled using 2T in 4 stroke engines and you should too. I have found no negative posts from anyone trying it.
I used it in my 2.5 common rail T diesel for years at 1:200 to compensate for the low sulphur content in modern diesel fuel which lubricates the HP fuel pump for the direct injection. Much quieter, smoother and better economy that more than paid for the 2T.
It's used quite extensively in diesels and there's lots of info on it if you look. The criteria for the 2T is quality, low or no ash and mineral is fine. The Lucas 2T sounds ok.

1:1000 is a very low, that's less than a teaspoon of it in a gallon.

We don't get the chirps in Oz because ethanol is still rare and not available in the grade specified but i've tried 2T in mine at that mix with no problems, not that I expected any, only benefits. I think it might even clean the fuel system and help keep the fuel fresh too?

Pennzoil also makes a TC-W3 2 stroke oil.

This is an interesting post about 2T, mainly in diesels but very positive about it's properties.
I have a few litres left and might start adding it again just to keep it sweet, quiet and for economy. It's Valvoline 2T Racing Oil to JASO FC, API TC and ISO GD

My chirping came back as well. Toyota did the fix about 1500 miles ago and they are back. But this time its more of a squeeking noise.

I havent been on in awhile, so I just read about the 2 cycle oil. I'm thinking about possibly trying it out, but does anyone know of anyother engine lubricants that might work as well?

I've tried Lucas Oil Ethanol Fuel Conditioner & Lucas Oil Fuel Treatment. Neither of them worked for me.
