Accepted Answer

Hi Douglas, Do you own a garage/work as a mechanic? Mechanics love this stuff, in particular, as I—not a mechanic but have had great ones—have been recommended this, by six or seven mechanics. I have to move a lot, in my profession, and love to keep up my 1986 MR2 MK1, for which this always does a great job, straightening it out...

Anywho, if you’re a mechanic, or otherwise, could you please tell me your reason for suggesting adding it, half a tank at time? I always like hearing different opinions, like that, and so I guess I’m wondering if it’s a result of some system of testing the additive timing you suggest, for this. Any help would be greatly appreciated — and don’t worry about quickness...

(... I last bought this, for $5, with Prime shipping, and right now, single packs are going for $15! Although six-packs are much better—at the regular $30, or $5 apiece—but there’s a **1-2 MONTH shipping wait,** on Feb 8... Glad I got mine, on Feb 7th... This is nuts, at $15/piece, or a 1.5-month wait!!!)
