PW R4360 Wasp major
Thanks for all the oil discussion. I'm still working on getting my R4360 running this summer. I've read this engine takes 100wt Mil spec oil and burns 130 octane gas. I'm not sure what size oil tank I will need to do ground running. I don't plan on running it for very long at each start and have been considering not installing an oil cooler. What size oil tank do I need to run the engine for 5 minutes or so at a time?
