The only harm ”from” ethanol is that it carries water in solution, then carries that water into the carburetor. If allowed to sit it will do nasty things. No additive or treatment does any good. Small engines have ventilated gas tanks, open to the atmosphere, open to collecting moisture...

Just buy E10 from a high volume gas station. Only buy a month or two’s supply at a time. Don't store the can on cold concrete because cold fuel with warm moist air condenses moisture from the air no matter ethanol or not. 90 octane (sic) won’t hurt anything, won’t help. When engine is designed...

Yes, that is why they didn't last very long. Flooded lead-acid batteries wear very fast when subject to a deep discharge. Lithium-ion doesn't like operating at full charge or low charge but is very happy in the middle. LiFePO4 costs less than lithium-ion, likes a full charge and discharges don't...

That is the old Craftsman trick of "upgrading" to higher battery voltages every few years. Sears sure is a success to be admired! EGo did a very good job designing one battery, right, the first time. Everything is 56V, and the same connection is used for all.

The EGo battery warranty is 3 years. Am still using my original 7.5Ah from 2016. The worst thing you can do is leave it on the charger 24/7. Second only to leaving it out in freezing temperatures. My 2013 Tesla Model S 85 still had 93% of it's original battery capacity remaining when I passed...

We learned during COVID. We won't tolerate such a police state... for a few years yet. Kill switches will not be enacted. We've been hearing of all these things since the Science Fiction genre was invented.

You couldn't bother reading the link before shooting off at the mouth? The supposed ban is of "new car sales". Infinitely (by political lifetimes) in the future when The Little Men In Power enacting this ban won't be around to actually have to enforce it. The same sort of Little Men today who...

The GL1800 was built in Marysville, OH. But if these "rice burners" can thrive on the not-really-reduced ZDDP then why not a US-built rice-burner Kawasaki at much lower RPM? My point is that if excessive ZDDP really is necessary that it is a design defect, other engines of much higher...

Zinc isn't limited by the EPA, it is phosphorous which is limited. Zinc only because they choose to use ZDDP in motor oil. Most "automotive" motor oils have 700-800 PPM of ZDDP. 1500 PPM becomes acidic so even the "zinc rich" oils are limited to 1100-1200 PPM. You ain't looking. Air cooled...

Not all lithium batteries are fire hazards.

Every motor oil has zinc in it. Most every engine ever made has (by your definition) “solid” lifters even those with hydraulic lifters. The issue is whether the spring rate and lift of the cam and RPM drive pressures great enough to push through the oil film. This just does not happen in power...

Neither Kohler nor Kawasaki have published a specification of what they expect of an oil... other than the video on Kawasaki's site saying to look for a genuine API rating and how they also submit to JASO for real testing (a snub at Shell who self-certifies a JASO MA rating on certain varieties...

Your theory is anecdotal. I’m asking for fact rather than, “lawnmower engines are different.”

I find most everything that is brave enough to list zinc content has at least 800 PPM. So, we are supposed to believe zinc works magic in lawnmower engines, trust that lawnmower-specific motor oils have massive amounts of zinc, yet no one puts their reputation on the line to enumerate how much...

Has been claimed, “automobile oil has no zinc” which is incorrect. If Kawasaki oil is so great for having zinc then how much does it have?
