I am conservative with additives. For fuel, I believe the best thing to do is buy "Top Tier" fuel, exclusively, if possible.

I do periodically use Techron, or one of the other brands like Gumout Regane that has the PEA chemical in it. I understand the PEA additives are the best. I only use them once every 10,000 miles, just before every other oil change. I also use a 2X dose, since I want a higher concentration. This regimen seems to have served me well over decades. I believe if you use Top Tier fuels, at least 90-95% of the time, a periodic maintenance use of Techron is all you need. Hello from your neighbor in Baytown.
