My Harley ran cooler with mos2 in the sump and every little bit helps with an air cooled engine.
My habit is now to flush any new to me engines. Once I'm satisfied the innards are clean I use a long drain oil,old ultra since I've got a stockpile and run it with ceratec for as long as humanly possible,then mos2 every subsequent oil change.
I'm not an idiot. And work hard for my money. I'm also open minded. If I use a product and it does nothing then I don't buy it again. Simple.
Cera-tec and mos2 have consistently proven fuel economy benefits in every v-8 I've used them in and based on data I've acquired with an IR gun they lower operating temps which in turn lowers oil temps.
I'm not trying to sell the stuff or convince anyone to use it. I'm merely sharing my experiences with a product.
I've used many different additives over the years. From slick 50 to duralube and everything in between. All of them were only purchased once because they did nothing to help fuel economy. Even used zmax with amsoil and nothing changed.
Yes today's oils are very well formulated and perhaps they are fine just the way they are however I've proven time and time again that an 8 dollar can of mos2 saves me hundreds in fuel every oci.
I proved it with my charger when I tested it last year. I proved it with my 99 silverado,which gained 150km per tank in comparison to before using the additive.
I have integrity and my word is my bond and the measure of a man. I wouldn't say the stuff worked if it didn't. That would make me a liar and mean my word meaningless,which as a man is unacceptable.
In the end I don't care if anyone uses the stuff. Don't if it makes you uncomfortable because in the end today's oils are very good. But for me I want that extra little bit more.
If mos2 didn't save me fuel I wouldn't use it. I'm not in the habit of burning money and if there was no return I wouldn't buy it.
My 16 air compressors and 7 generators get 1/4 can of mos2 every second oil change.
I've got 2 compressors with very high hours. By my count the oldest has a nominal 15000 hours on a Honda 5.5 160cc engine and the second oldest has a nominal 12000 hours on it.
My service guy says they are rated for 5000 hours before requiring rebuild. Mine have had nothing but oil changes and a frankenbrew fuel additive of my own design.
These 2 compressors run 10 hours a day,6 days a week and have never required so much as a gasket replacement.
When I change the plugs they are clean,so that kinda flies in the face of arco who swears that mos2 will leave deposits.
Oh. I almost forgot. I was asked to look at the plugs in my charger which used both mos2 and has had ceratec.
After 35000 miles with either one of these products in the oil or the other when I checked 4 plugs yesterday the plugs had no deposits whatsoever. None.
Car now has 85000 miles on it.
So I'm satisfied,even if others aren't. I'm not trying to change anyone's minds,I'm just sharing my experiences.
And yes if I found that the results were negative I would share them with the forum to potentially save another member from harm.
