My original post on the page before had more details, but here is even more
First, I like playing with stuff. Is this NEEDED? Probably not. I also don't need to spend so much on flashlights 😁
Second, there was a post on a forum somewhere. I don't remember if it was here, BITOG, Smokstak or maybe even Ziller, but someone who worked for FEMA had 10+ Honda generators that ran for a Hurricane, I think it was Ian? I know it was in Florida. Either way, they had multiple engine failures even though the engine oil was changed at the interval required and the engine oil level was always good. Honda ended up covering them under warranty, and advised to run thicker oil than 10W-30, as the extreme temperatures of the deep south and the load on the generators had sheared the oil down to be too thin to properly lubricate the engine.
So, after much discussion and reading forum threads, I decided to run 15W-40 in the generator.
15W-40 on a pull start, in freezing temps may get very tough. Also, I worry about the wear on the engine during the first few mins. This will do a GREAT job at heating the oil, so there is little downside. This entire project cost less than $20
Yes, I could just swap the oil before winter, but that just seems like so much more work, and a waste of oil
