I use Costco fuel in my cars exclusively, and have never had a problem. It’s Top Tier stuff, so tossing an occasional bottle of Techron in them is a waste of money.
I’ve never looked, but i wonder if there is an equivalent for Top Tier fuel in diesel? I tell the eldest boy to always fuel up at our local Shell. The price is competitive and it’s unlikely they would have crappy fuel. It’s a busy place and turns fuel over pretty often as well. -D > On Dec 23, 2019, at 8:50 AM, Mitch Haley via Mercedes <mercedes@okiebenz.com> > wrote: > > >> On December 22, 2019 at 10:41 PM Curley McLain via Mercedes >> <mercedes@okiebenz.com> wrote: >> >> >> the only one I'd use is techron, but if you follow Mitch's advice, I >> don't think you'd need any.
