Oils are designed to hold "stuff" in suspension, up to a point. If you have "stuff" on the bottom of your pan then you aren't changing your oil often enough. I have never seen the need to run an engine before an oil change. All of the oil has already drained to the bottom of the pan from the last time it was run. Oil at below operating temperature will take a bit longer to drain out but this isn't really an issue. I just let it drain till it stops dripping, while I read the paper and have a cup of coffee.

Thanks everyone. I found this on You Tube Oil Change on Drive2 and it doesn't look that difficult. I'm also going to add a Fumoto F109SX M12-1.5 Sx Series Drain Valve to make it easier.

I'm going to attempt it in April when I change the oil in my other cart.

How do you dispose of the old oil besides reusing it in an outdoor power product?

I catch it in one of those disposable aluminum pans (10 x 12 x 2 1/2) and transfer it back to the bottle I poured the new oil from. Then you can take it to an auto parts store or Walmart automotive for disposal. I usually wipe out the pan, then wash with soap and save it for next time but you could just throw it out.

BTW, you do not want to mix it with gas for 2 cycle lawn equipment.

Oil Pump
 

I had the vacuum type of extractor and it works fine. I just found it a difficult to clean to my satisfaction.

I just purchased an electric pump that clamps onto the battery. It pulls the oil much quick and goes easily into an empty oil bottle of milk container. The same unit on amazon is sold at different prices depending on the seller.

Used it once so far and loved it.

Exactly correct. Just did this. But on the other side, no filter either. Think a filter would help those draining out fill tube, but probably have to drop pan to get to my imaginary filter….

2022 and 2023 Yamaha

I just looked up the owner's manual for a 2022 Quietech and see the Available Viscosity Index on page 20 showing 10W30 & 10W40. This chart is not in my 2014 or 2018 manuals. Both manuals list only 10W30 in multiple places.

The emission control label on the frame near the engine on the 2022 says 10W30 according to the manual.

Well there you go, now it’s as clear as mud! I was puzzled by the 10w40 because the only time I’ve ever used 40 weight oil it was in diesel engines.
