Sea foam

The guy at autozone told me it's safe to put a full bottle of seafoam into my truck lol. Is this true? And does it help MPG?

Sea Foam has been around forever. When I went through a two year automotive technology program back in 99-01 the old mechanic that taught it swore by it. (So do a lot of old wrench turners).
They claim it cleans up all the gunk. It definitely doesn’t hurt anything. It may help a little. There’s probably not as big a need in a modern 4.0 liter as there was in a less efficient slant 6 Dodge or 351 Cleveland though. AutoZone has it on sell right now. They were trying to get me to buy some too. Lol.
 
I tried a full bottle in my gas tank.. I didn't notice anything. I had a friend with a silverado that ran rough and he put a can in his gas tank and said it helped.. Idk though
 
My Honda service rep told me Honda tested a lot of different additives and came up with the best thing that could happen was nothing and it goes down hill from there.
 
Depending on how many miles are on your truck or rather how much carbon has accumulated in combustion system & on a lot of high mileage motors with heavy build up sea foam can work great quite a few on tw had good results, basically you can do the same thing with ATF...
 
I'll add, you guys with newer trucks shouldn't even bother , not enough build up usually to warrant it...
 
For the record I don't advocate dumping any of that "mechanic in a can" **** , maybe in a high mileage motor (with nothing to lose) I'd try it but using it (seafoam ,etc has it's own risk of breaking loose large amounts of carbon & some of those chunks will hit & CLOG oil passages in the top end & worse the lower end, it takes but a few seconds of no lube on the crank journals /rod/cam/etc: to melt your engine , seen it before...
 
I had an 85 Nissan pickup back in the 90’s that was running pretty poorly. Talked with a mechanic and he said to try a bottle of BG44K before he tore into it. This is something similar to the Sea foam. Totally cleared it up. I account this to carbon build up with a high mileage vehicle. If you have it in your area it would be something to try. Worked for me. Good luck.

Perfect candidate for this, besides it's a nissan if it blows up who cares....haha just joking but yeah your truck was a good example of good results...
 
Just be careful it doesn't poison the catalytic converter. letting all that crud loose into the exhaust can coat the catalyst.

I don't think that'll happen If you just pour in the gas tank? Now vacuum line is a different story.... correct me if I'm wrong guys.
 
I' forgot why you guys were dumping that **** in your tanks in the first place...:confused::confused:
