Engine Additives

So I’m wondering about engine additives for 3rg gen Tundras.
Nothing crazy, just products that help lubricate, protect from breakdown, gas system cleaners, etc.
In my wife’s subie, we were told by a Subaru mechanic that their engines don’t really get along with aftermarket additives, I’m just wondering if anybody has any info on this topic when it comes to the Tundys.

 

all you need is to use top tier gas and change your oil every 3000 miles

 

Nothing in my Tündra

 

be sure to use full synthetic oil, don't add anything to it

 

I use Mobil 1 full synthetic 0W-20 and don't do anything to that, except to change it regularly. I have in the past put stuff to get water out of gas right before winter hits full force. I also put silicone spray all around the weather stripping on my door to keep the door from freezing. I see the benefit of silicone, but I see no benefit/difference from gas additives.

 

Every so often I add Seafoam to my gas to take care of the injectors and deal.with any water in the gas. Been doing this with my 2002 for 15 years.

 

Agree with others..
top tier gas, oil changes per Toyota's schedule, seafoam in the tank couple times a year (great stuff)

 

Do you just use half a can the fill it up?

 

Seafoam or Lucas upper cylinder. Just a few times a year. After tearing into a motor that used sea foam and Lucas,I was amazed at how clean it was.
