I agree Tiger, That is where marketing misleads many people. A sealed container such as a 1-gallon steel fuel can does not get oxygen in it. With plastic fuel cans/jugs all bets are off.

Hello B., I like Marvel Mystery oil, and it has been a proven product for many years. It started out as a carburetor treatment way before any of the other modern "snake oil" product came into existence. It is actually a "Stoddard solvent" product which melts down carbon and gum deposits. Many...

Welcome C., Welcome to the forum. First, the make, model and hood label information does not provide good information in most cases. If you need help with a machine, make sure that you include the product chassis label information and the engine label information. The manufacturer of the...

Hello M., Welcome to the forum, If you need help with a mower, please include all the product information off of the chassis label and the engine label or drive unit label. The engines and drive units are not made by the mower manufacturer. The more information you can give us initially the...

These castings are made by a casting procedure known a "lost Styrofoam" casting and it often makes some strange impressions in the aluminum metal surface that can be perceived a faint crack, but they are not a crack. They are literally a pressure seam. Back in the cast iron days they actually...

It sounds like the oil is aerating and foaming due to a bypass condition in the pump(s). This could be a blocked filter/screen condition or worn internal pump parts. Lower the reservoir level, then run it and pull the cap and look for foaming

As the title suggests, stabilizer in fuel means it will last forever, right? Read on. Do you just dump a best guess amount of stabilizer in the fuel tank(s) or fuel cans? Do you think "more is better" will make fuel last longer? It does not. Follow the direction on the product container. Is...

I think he is referring to oil purging out of the drive reservoir tank.

Hi Skippy, Given the two choices, I would go with the full synthetic and do not use any additional additives because the oil has a sufficient amount already. For most units I personally use 20W-50 regular conventional oil. It works well for me down here in South Texas

This is the exact issue when we don't have a PIN to go by.

If it is just homeowner occasional use, Ryobi does pretty well from what I have experienced. I do not recommend them for commercial use because they are just not that built for that. The advantage of battery power tools is no mixing fuel or dealing with tune up. The disadvantage is the...

Hello G., Welcome to the forum. What we need more than a year model is the product information number (PIN) label information off of the chassis. The label in on the front side rail on some models, but many of them have the label hidden under the fender between the tire and frame. John Deere...

Hello Skippy, Oh No! Not the "evil Zinc" .... Just another scare from an uninformed individual who has been misled by rumors that Zinc is some kind of "destructive" additive in oil. The dealer of all places should know better, but people are quick to believe bogus rumors instead of reading the...
