Oil type

[Done Deal]

I have a 02 Club Car DS with the 290 motor. What kind of oil do you guys use or recommend. I used to use Mobil1 5W30,but the guy that does some work on my cart does not like using synthetic oil.

I use the stuff in the blue containers from Wal-Mart. Been using it (non-synthetic) in various weights for years now. I use it in everything I own and in various weights and have no complaints. (Super-tech?)

I run 10w30 in a cart similar to yours.

There will be 10,000 different opinions on this topic.

Shell Rotella 15-40 (diesel oil) still has most of the additives that small engines need. Remember, they are built to much loose tolerances than todays liquid cooled engines.

I'm with mooncarter. I use the blue walmart supertech, but I use the full synthetic in everything. It's just as good as anything else, and can get a 5 qt jug for around 15 bucks. I've got 270k miles on my car and been using it for the last 150k miles, no problems. search on youtube for project farm, the dude has done all sorts of testing on all sorts of oils. i was actually pretty surprised how well the supertech held up against redline! Actually some pretty neat stuff.

Proper Oil weight depends on your climate. Yu can run 10w-40 or 15w-40 ere in the summer time. Those are too thick for spring, fall and winter use in VA.
I run plain SAE 30 in all of mine year round.

You can run synthetic if you want, but it's not really beneficial for these. Fuel dilution is a bigger issue than oil breakdown due to age or heat. As good as synthetics are for heat, they are still no better when it comes to handling fuel. The main reason for an oil change with these carts is that fuel in the oil causes it to degrade.

Engines with tappet valve drives also benefit from having zinc in the oil, which synthetics usually don't have much of. Run a regular conventional style oil and change the oil and filter when it starts to get kinda dark. It will run almost forever.

If you really want to understand the chemical differences between syn vs conventional oils go to the net and read tons of info by people who really know what the are talking about. The differences are huge when comparing heat stability,mechanical shearing,metal clinging properties,and stability to fuel dilution. There is good reason why all mfgs now require syn oil. As far as the zinc content diesel syn oil has it still in the formulation as the don't have the cat converters that zinc can foul. P.S. I did a bump of my yamaha G14 engine look inside after 350 hours running on syn oil. No sludge anywhere. Do note the cylinder was out of spec when I did a ring and rod bearing redo when purchasing the smoking cart.

Ive always ran synthetic in my carts (12 precedent 350 and 09 EZGO RXV). I like Rotella T6 540. I run my carts all year round if there is no snow. And I have them turned up a bit so I feel better with the synthetic.

After tons of research I run rotella T-6 in all my small engines year round also.

Thanks for all the great input guys!!
