Regular oil for the first two oil changes (since it is better at picking the metal burrs and shavings from manufacture), synthetic from there on out.
The engines that really need synthetic are the generators that use splash lubrication (read, all new Onans, and all portables.) Those tend to be very hard on oil, so might as use the best one can, since they don't use that much.
What a bunch of horse pucky! Do you really think because car # 48, 52 and 75 use xyz synthetic oil, your vehicle will run smoother, faster with less wear & tear? Come On!!!
I'm not a fan of full synthetic oil. I use Shell Rotella (non-synthetic) in my Duramax as well as my Onan. My last diesel truck has 350,000 on it now and is owned by my son in law. The Onan oil specs includes Rotella so why not use the same oil in both. Much easier that way

I have used Synthetic oil in my vehicles since day one..
Ford Escape 198,000 miles and going strong...
Ford E250 145,000 miles and going strong...
I also use it in all my equiptment...
Maybe it's me, maybe it's the oil, maybe it's none of the above...
Thanks again. I didn't think about useing regular for first two changes, and then switching. That makes sense.
I don't agree with the horse pucky guy. Synthetics are proven. RVs are a huge investment. The last thing I want is for my home to break down on the road somewhere for want of a few bucks a year.
