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 took our Cart to the LSL garage for a once over and fix anything it needed. I received the bill, paid it and while walking out noted I was being charged for an oil change and engine tune up. I am as further as you can get from being a mechanic or anything near it but do know you don't change the oil on an electric cart and tune up the engine? I went back in and asked the Manager what was going on. He said he was terribly sorry and that the Mechanic just pulled the wrong code when filling out the forms? He adjusted the bill to account for the error. Net: Always check your bill!!:ho:

The owner's manual for my 2014 Yamaha cart calls for 10W30 Yamalube oil. I change the oil myself every 6 months.

Did the manual say what weight the Yamalube was?

IMO either our will be Ok.

Hi, do you have the name of the mobile guy to do oil changes? I am on my second stay here in the villages and would like to get the oil changed. Thanks, Mike Zaharoff.

I would ask the service people if they have another brand of 10W40 oil that they use for oil changes. I would be surprised if they use the Yamalube brand of oil. It's too expensive.

Rod bearings and piston rings take a lot of abuse in a golf cart engine from constant stop/start shock loads. I would not use an ILSAC rated oil in these engines. Use HDEO like Rotella 10w30 or even 15w40 with their high wear additives like molybdenum, phosphorus, and zinc.

Yamalube 10w30 will be fine even in the summer heat. I hear a lot of rod/piston slap during takeoff from golf cart engines that haven't had regular oil changes :)

The noise might be the result of decreases in the operating temperature viscosity as the oil ages. Synthetics behave better than conventional oils in this regard. I suspect many people don't follow the manufacturer's recommendation on oil changes.
