I could probably still be running the original air filter and spark plug (with cleaning) in my GC due to air not that dirty in my area of villages. (MY Yamaha C3 scooter had 8K miles and 5 years on resister spark plug until it had weak/intermittent spark, resister was burning out) ( now that I don’t ride it that much (hardly 200 miles year I still change oil due to short trips which contaminates oil)

Fuel injected carts burn cleaner and spark plugs can last long time. One thing I would never do leave oil in lawnmower design engine over year regardless of miles or hours due to poor design combustion which contaminates oil. Quart of oil cheap peace of mind to me. Admit Yamaha gas golf carts if governor not tampered with run at pretty low RPM but they still produce heat on hot days which affects condition of oil over time IMO.

I can look at engine tell it oil been changed/maintained as often as should, it’s dirty, creasy, signs or oil out all seals to me meaning oil was ran too long and dirty oil eating up crankcase seals. I like my oil working for me doing CCLs. Not working against me and life of my engine

I use Titan got golf cart annual maintenance. Had it yesterday $177.17 and looked over my second cart and jacked up speed so electric bikes don’t whiz past me.

Oops
 

Should be $117.77 for titan .

I did too, twice. Never again. He charges $90 just to come out for the service call, no matter what. He charges for the service, on top of that $90 fee. The service may or may not solve the problem but if he has to go out to fix it again because whatever he did, didn't work - it's another $90 plus whatever he'll charge for the service.

My cart stopped moving. It'd had problems refusing to accelerate when I hit the gas pedal, and finally "turning" and "catching" and moving. This was sporadic, so I mostly just ignored it and considered it an idiosyncrasy. Until one day it just stopped moving. Had it towed home. Michael came out, replaced the battery and adjusted a bolt under the seat (where the engine and everything else is). All seemed to be well for a few weeks.

Then it started doing it again, again - sporadically. So I just let it be. Around 6 months later it conked out again. Called Michael. He replaced the bushings. Another couple hundred bucks (including the $90 for just showing up).

And then, it happened again. Got the Villages Golf Carts to check it out. Turns out, the cables connected to the battery were bolted on upside down, causing them to jerk and loosen whenever I sped up or stopped. In addition, some other cable was loose, and apparently had been loose the whole time. So they tightened it.

It's been trouble-free ever since and cost me less than $50.

I do it myself, basically change the oil, filter, spark plug and check the tire pressures. I checked the tire pressure periodically.

Darn. So far so good for me in the past, usually every October. But no real problems, just regular maintenance. I guess they all fail sooner or later.
