    Just bought 16’ 4Runner with 38k on its 4.0 - Carfax shows regular “stealer” service history

    Lots of debate about Seafoam tundras.com page - I’m putting it in my 18’ tundra fuel tank every oil change- 5k- only done one-have not put in oil yet??

    Like to do as much as my own wrenching as possible

    Wanted to see what u 4Runner guys are thinking on using Seafoam????

    Especially in this situation were I don’t know vehicle history- is it ok to put in tank / thru dirty fuel system @38k - will I have to change a fuel filter etc.
    That could collect debris broke lose by Seafoam???

    How bought in crankcase @ oil changes- I have herd to use just before oil/ filter change- so u get fresh filter after run thru
    Any other possible issues??

    Thx for ur thoughts

    No thanks. Not in a vehicle that new.

    That being said I have used it in my 88 that has 310k miles. Did it do anything? I couldn’t tell.

    Seafoam is excellent in carburetors but I not sure of it benefits in EFI. Run a tank of premium high octane every once in a while. But I agree with the above posts, I wouldn’t use it in that new of a 4Runner.

    LEDs all around, otherwise bone stock.
    Ive used it a few times & feel it helps (50k and 100k miles). But the guys who have been doing this longer than me like Lucas oil or Techron better. A much bigger waste of money ($200) would be doing the recommended fuel injector cleaning at the stealership.

    I used it last week in my generator that I forgot to drain the fuel out of for a year. Poured in fresh ethanol-free fuel and 1/4 can of seafoam and it belched black smoke and barely ran for about 3 minutes, then started running better and better. Now it purrs like a kitten with no smoke. Used it in a couple of ATVs and motorcycles that had been sitting for a while with bad fuel and got similar results. But for a low-mileage Toyota SUV? Likely a waste of money.

    For most vehicles specially newer ones snake oil in my opinion. I do and/or have used it in mowers and things, hey if it f's up a Toro I'm out 300.00 not thousands! However I'm also anal about storing all power tools with the "tru fuel" you can buy at Home Depot. I am not a mechanic and do not work on my own vehicles but I'd be nervous about putting it in oil just my .02
