No need to sweat it, 10w30 will be just fine.

I agree. I have a Honda CR-V and an Accord. I decided to change my own oil. I asked a former Honda service manager what he recommended. He said he used 10W40 in the summer etc. I then looked in the manuals and they both said to use 0W20 all year. So I would imagine 10W30 would be fine for your cart. Just change it when recommended.

They don’t package it either, they purchase it from the lowest bidder and furnish the containers, the packer delivers it to their distribution center and Yamaha sends its out, use any synthetic 10W 40 that meets Yamaha standards (any Yamaha oil package has the standards listed) just clone the standards!!!!!!!!!!!

You only need to change the oil once per year. If they change the oil they take responsibility. I have a 2018 and it’s fine.

Why even bother with them? There are a couple of "bring the service to you" golf cart mechanics in the area that will do the oil change at your home, and probably for less money. I'm sure they could supply the oil you need.

If you're interested, I use Todd Casey Cart Repair to service my cart. He comes to the house and does an expert job checking out my cart and changing the oil and filter. 352-465-3934.

I don’t know where the “70 degrees “ came from. 10w-30 oils are designed to optimally operate at 210 degrees which is a normal operating temp for an internal combustion engine.

So I went to TV golf cart LSL. Asked to purchase a quart of 10W-40 yamalube oil. They told me they didn't sell 10W40, just the 30. I said, but we will be in the mid 90s the whole summer. The Manuel says to use 10W40 in these temperatures. They had no answer for me other than, we only sell 10W30. So the oil changes they do, break down after 70 degrees. Tell me how how many engines get ruined by this practice. I'm going to buy the 10W40 for my oil change and do it myself.

I certainly didn't know this so thanks for the info. Question, does the engine have a plug at the bottom to drain the old oil? When I had my oil changed(the first time since I bought it), the guy used a suction pump thru the oil cap on top of the motor. I need a change as well but I'm being told I don't need it at 2,000 miles after the first change. Not sure.

If you go elsewhere, watch it doesn't negate your warrantee.

excellent plan. or get amsoil 10w-40.

Yep. I use Mobil 1 both oil and filter. The filters are rated for 20,000 miles, the oil 10,000. I change both at 10. However the wrench comes on at 5,000. I wonder why? Could it be they want you to pay for something you really don’t need. No, they wouldn’t do that.

[Ramone]

Yes, Amsoil is the best. I've used it in all my engines since 1976. Vans, cars, motor cycle, ATV, snowmobiles, Carts, lawn mower. They all run till they rust apart. Plus drain time is extended.

I change the oil myself. Buy the cheap12 V pump from eBay-$25. It goes into the dip stick, works great. I was told change every 100 hours & it will last + 20 years. Nice & BLACK oil after 100 hours. I can't imagine going 500 hours between changes, that would be every 3 years?

[bilcon]

Never had a problem with my 2013 Yamaha and always have oil changed in TV, once a year.

I would never consider using a 10W-40 oil in this age of synthetic oils. A quality full synthetic 0W-30 or 5W-30 will give you excellent start-up protection and once at operating temperature, excellent flow for cooling and extended wear protection. Today's 30 viscosity synthetics have much better high temperature shear strength than a conventional 40 viscosity oil. The only reason a 10W-30 oil exists is becasue they, before synthetic oil chemistry, couldn't easily make a 5W-30 oil. The only reason you can still buy a 10W-40 oil is because there are still some really old engines around whose manufacturers at the time recommended it. There is no good technical reason to use it.
