Hey, all,

Should I use a fuel cleaner for my ES300? If so, what kind? Also, should I use synthetic oil since I have over 150k miles?

Thanks.

Everything I have heard is that Toyota actually suggests to not use Fuel Injector cleaner. I do however use Ethanol treatment as I have seen what it does to motors.

seafoam it and run premium for a tank or two.

and always use synthetic when you can. doesn't cost much nowadays anyway

I would say do not add fuel system cleaner if you have the OEM Fuel Pressure Regulator. Ask me how I know :eek:

If you feel you need to use fuel systems cleaner and can find it locate BG44K, it is Techron on steroids. But like I wrote, take care it may clean too well.

My local Toyota dealer's parts department recommend I use 10w30 Conventional. But it depends on your climate, I use to use synth but always had leaks, I swapped to conventional 10w30 Toyota brand and the leaks stopped. She seems to be quieter and smoother to boot

I've ran injector cleaner a couple of times.

Other than that, i'll get some octane booster once in a while.

Seafoam is great!
