I was thinking of buying the BG44K but figured I would try this first. Car felt totally fine on the way home. With the RP its even sold at Walmart. Super easy to get and only $13.47

Thanks for the info I've alway put Lucas cleaners in my cars just been hesitant on doing it in the F. Works great on my SC with a 1jz swap though.

I noticed with my new oil cooler setup the start up isn't loud and obnoxious like it was since I bought it, much calmer, likely cause the oil pressurizing

I know some will think Im nuts but I feel like when Im at idle at a light I dont feel the cars slight idle vibration as much. Seems to idle smoother. For $13 its a no brainer.

Well for my car (GCC Spec) Lexus forces you to put in injector cleaner every 10k km.

I get a warning light "injector maintenance", when I asked Lexus what they do they said simply add an injector cleaner.

So I've been doing this every 2,500km for the past 30k km. So far so good.

My car used to hang when driving on the motorway at a constant speed. Ever since putting in the injector cleaners the car has performed better.

Thanks for posting this. This carries some weight. Im going to keep using it every 5-10k miles. I cant even feel the car idle anymore.

I actually just bought me a bottle and pour it in along with filling up the gas tank. I do notice slightly better response and a little smoother pull. I will see in the next 200 miles.

I ran a can of BG44K, which has always been my go to for serious cleaning, and it made no difference at all.

Sea Foam is great, I use it in my Toyota Highlander.

They have that at Walmart too. I'll check it out. Went with RP because of the reviews and all the hype on the forums.

I know nothing about sea foam , other than it has a weird name. Is there an advantage of using that over the traditional stuff??

I think Seafoam $7.99 at Walmart. Seafoam have been around for a long long time. Try it out.

I was thinking of using a little bit of SeaFoam with 100 octane in the 'F' and see what the results are like.
