We have tried Redline, Royal Purple and Mobil 1. We have never been able to document a 0.01 gain which would be about 1% in power over Valvoline. Tenths stretches credulity.

Complex words like 'credulity' are not allowed here at 12:57AM in the morning. Can't be used until 8AM - after quiet-thought hours have elapsed.

I do agree with you a vast majority of the time...... at any hour of the day. I've stretched my tenths countless times.

Unbelievable..........................


Yes

Assume what you want. Probably from two individuals/members here that never used QSUD or think Super Tech Syn is the next best thing since sliced bread -- being its price!!! Lol

About like how some of the Motorcycle guys argue about how the clutch 'responds' between brands and grades of $12/qt. boutique oils.

The only time my bike's clutch ever 'responded' to me was when I dropped a hit of acid in the crankcase.
Come to think of it, that was the same day the bike and I had a long conversation with a sunflower.

The QSUD does have a lot more Moly, maybe too much.
