I can sense the next question brewing.....

"What's a centistoke?"
"And don't talk SH** because I've searched!"


Thanks for the list INDYMAC
Funny how Honda recommends MTF while this is thinner than a .. okay temporarily allowed... 30 weight.
(No VOA of MTF-III?)
It must be the additives then...?
Nice to see Amsoil being close to a true 30 weight, WITH the additives.
No surprice it works well.

For the most part, the chemistry is very different for these fluids when you compare VOA's. But they all seem to get to the same end. I believe Honda MTF was probably close to a 30wt. The Honda MTFII was probably a response to all the notchy/grinding complaints when the original MTF was cold, and another "one size fits all" attempt by Honda.

I get annoyed when people don't search. I thought that the only thing more annoying was when people don't search and say they did. I was wrong.

Adding a thicker oil to a transmission will give hydraulic "support" to the synchros, hampering them from doing their job.

Synchros have razor sharp brass teeth, in a stack, that cut through the thinner oil to grab and stop (synchronize) the next gear. Adding a motor oil will protect your gears for a short drive, but if left in your will surely damage the transmission.

Bottom line, only use a motor oil if you drained your MTF out, disposed of it, now a family member needs to go to the hospital and you need your s2k to transport them but have no MTF.

ALWAYS use a high quality MTF designed for synchronized transmission use.

Personally, I have had fantastic results with Honda MTF, in my car and hundreds of others.

NOTCHY shifting is 95% clutch, disengagement, and driver habit related. Not internal transmission or fluid type.
