| Raised Hands Surround Us Three Nails To Protect Us  |
They have a formula for GDI motors now. https://seafoamsales.com/produ...-top-engine-cleaner/ I have not used it in ages. Newer vehicles I just dump Techron in the tank and fill up with Shell V Power every couple of months and drive it very spiritedly. Many moons ago I used it on my 96 Mustang GT that had a funky idle I could not get rid of. I did the sucking it in the vacuum line and letting it sit for awhile method. Talk about a smoke show folks! And sure enough that idle smoothed back out. Engine ran a little better after as well. So I say it worked. My 2000 Silverado is due for an oil change so I have been thinking about dumping some in the crank case a short time before the oil change. ———————————————— The world's not perfect, but it's not that bad.

My small engine repair guy swears by it. Therefore I use it in our generator, lawn mowers etc. ------------------ Eddie Our Founding Fathers were men who understood that the right thing is not necessarily the written thing. -kkina | |||

I would not use it in any turbo cars, specifically Ford Ecoboost engines. Jesse Sic Semper Tyrannis | |||

Since no fuel is washing the backside of the intake valve, how can the grade of fuel have anything to do with keeping it clean? The buildup is caused by blow by. No fuel additive will reach the problem. I’ve read that a vapor catch can will help. It’s surprising that we’ve had crankcase filters on big diesels for years, but they aren’t found on DI gas vehicles. Demand not that events should happen as you wish; but wish them to happen as they do happen, and you will go on well. -Epictetus | |||

I use it in my small engines as a gas additive but not in modern car engines. I'm Leary of adding things to these highly computer controlled engines where there are sensors at seemingly every path fuel takes to the combustion chamber. Maybe that's over thinking it but a tank full of Chevron with Techron every 3-5k miles or just a bit as an Techron additive is about as far as I go with our vehicles. However, I'm sure Seafoam won't harm any engine if used in the proper dilution, so if you like it, go for it. Men fight for liberty and win it with hard knocks. Their children, brought up easy, let it slip away again, poor fools. And their grandchildren are once more slaves. -D.H. Lawrence | |||

I got introduced to it when running an old Johnson outboard on my 14' aluminum boat. I never saw any change either way when I used it. Fast forward 5 years and I had a half a can left and I bought an older John Deere Garden tractor that had a bit of a rough idle to it. I saw some guys recommending it for this symptom on the JD forum. So I dumped the half a bottle in the gas tank and used the tractor with no difference noted. The tractor then sat a week or two and I went to use it again. I got the giant white cloud that I've seen others refer to that use it on small engines and now my JD purrs like a kitten. I think it has its uses, for certain small engine situations and has to be applied like I did this time in that you run some through, and then let it sit. | |||

DI engines will always get build up on backs of valves, not much you can do about it. Blow by is a real concern on TDI engines because it dumps PVC valve right onto your intake valves. If you have a TDI engine I highly suggest a catch can. All that stuff from your crank case is getting all over your valves. The claim is premium fuel burns cleaner/more efficient so there is less vapors left when the valves open. My car is a TDI, I wish it was a multiport set up. Jesse Sic Semper Tyrannis | |||

Techron was on sale today. BOGO. So I bought two. Just tossed one in my tank. I didn't know Techron made a high mileage version. | |||

| Woke up today.. Great day! |
I think Techron is one of the BEST in tank injector cleaners on the market IMO. I have been using it for over 25 years. | |||

Pretty sure that is the consensus. Jesse Sic Semper Tyrannis | |||

You DO NOT want to put seafoam in the crankcase. It is not made for that and will dilute the oil, wash out all of the bearings and dislodge and gunk and possibly clog the oil pickup. | |||

Could you clean your guns with it? Maybe not the barrel. | |||

My Seafoam story. I have a custom built 500 hp engine in my C5 Corvette track car. The engine was getting a slight knock at WOT. Engine builder looked at fuel delivery and suggested that I use Seafoam. As the engine idled, I slowly poured a half a bottle into the hose on the vacuum side of the PCV valve. Engine eventually died. I let it sit for 30 minutes. When I restarted the engine, it blew a cloud of smoke so big and thick you could have hidden a platoons movement in. LOL I ran the engine until it quit smoking. Once it cooled down, I changed the oil. I went for a drive and no more top end knock. Viola. Later on, I also added an oil catch can to mitigate the problem. | |||

In 2010 I refurbished a 10-year-ignored 2000 Acura TL with 105k on the odometer. Plugs, all fluids, tires, trans 3x3, Seafoam, and a return to premium fuel (plus replacing the original *eeewwwww* cabin air filter). The engine then ran like a precision sewing machine for 70k miles until I traded it for a truck. So I'm another one of the "praisers". | |||
