My 2017 sunseeker with e450 chassis calls for 5-30. I used Mobil 1 for the last oil change.

Mr. Deuce I see your posts...so I know you have knowledge...prolly more than most. I spent lots of years dealing with parts and repairs on many types of cars. I have seen more than I remember and I have seen and heard many complaints of Ford oil problems beginning mostly with the 4.6L V-8. The problems were real.

Now the reason they had problems was because of failure to follow OEM specs and service intervals.

You can look it up or ask someone.
Then those were not "Ford" problems, they were John Q. Public's problems.

In my SOB 33ft., '08 V10 I use Shell Rotella 5-40 T6 full synthetic. In the gen-set, I use Shell Rotella 15-40 T4. These engines are like boat engines, always running 'uphill', always loaded.

I have an older Georgetown 359t motorhome, 2004 to be exact. V-10 which had 21000 miles on it when we bought it in 2015. It now has 30000 miles on it. MFG said to use 5w30 but as of 2 years ago a bulletin came out in favor of 5w20. I use Castrol Edge full synthetic 5w20. I use the Ford oil filter. As far as the Onan, look on Amazon for the complete change kit which includes 2 quarts of Onan oil and an Onan oil filter plus a new air filter! Great price too! Hope this helps.

That's a good deal but the Onan 4000 in a Class C does not use an oil filter. If so, I haven't found it yet!

Very good information. If I owned a motor home I would change my oil by time not miles. How long does it take most owners to put 3000 miles on their rig? I think six months would be my number. I would use recommended grade synthetic and an OE filter. I would not worry about name brands. I would pick a store brand and stick with it. I use Pep Boys oil. Some major oil company is probably making it any way.

That just doesn't apply to Motorhomes. That is all new modern engines. Gas and oil burners! They do more with engine oil in the engine then they ever did in the past. Old push rod engines are pretty basic compared to any of the modern engines. That's why the proper maintenance is so important.

First class A, 2000 model year I put 10K miles on the older V10, second rig my Georgetown 25K miles the newer V10. I changed my oil once a year because I was like most of us and drove less than 5,000 miles per year. I always used 5W-20 as the oil cap on the V10 stated and bought semi-synthetic on sale including filter at Advantage Auto Parts, or the best deal on oil only at Walmart. For the Onan generator, I used straight 30 or 10-30 based on the capacity label on the genset and changed out the oil filters every other year because of the limited amount we used the genny. When I traded in my Georgetown, I left a note for the dealer prep guys that the genny had frestt oil and filter (Napa Gold $16) with zero hours on the fresh oil and the engine had the mileage to the dealer, about 7, on the fresh engine oil and filter.

With now having a diesel engine rig and diesel generator I plan to take the rig somewhere to have the engine oil and filter(s) changed yearly and I plan on doing the generator myself.

I marvel at some RV'ers putting expensive oils like Mobil 1 or Rotella etc. in their gas RVs and generators. Why? You are not going to be driving that rig for 250K + miles where the minute differences, if any, will play into the longevity of those engines. And, if you change the oil yearly, or every 5,000 miles you are taking care of the engines better than Ford or Cummins expected in their service guidelines and expectations. But, like another thread on this forum going on where some folks are using 7-11 polymer wax type products on their RVs at $80 a pop, and some use good old Turtle Wax from Walmart at around $5 I guess its what you think works best, for You.

Oil is oil, it's the additives that are different.

Do your research. Look at everything, don't forget to check Amsoil with all the others. Personally I use Amsoil and have for almost 20 years. No problems with cars, diesel pusher, generators, or small engines. You will only be happy with your own decision, and if something happens you have only yourself to blame.

I am wondering if generators without filters should have non-detergent oil in them?

I take it you never opened up an early 50s engine without a filter or non detergent oil! Not nice. I use high detergent oil for every engine with out a filter to keep sludge down.
