I don't think switching oils will keep the temps down. The air cooled oil is just rated at a higher temp before it starts breaking down. I have done research into air cooled engine dynamics, as well as speaking with a few old school VW and Porsche mechanics, and they all say the same thing, air flow. The old air cooled Porsche cars had large louvers to direct air in and out of the engine compartment. I would recommend an oil cooler since you are running out in the desert, but you can get by if you keep the buggy moving. For my application, slow trail riding will not allow adequate flow, so an oil cooler is the preferred fix, as long as there is enough air flowing over the cooler. For this, I am routing the cooler to grab as much air as possible, and also adding a 100 cfm fan to run at all times for slow speed operation.
