have a motorhome with Triton V10 6.8. After how many miles should I change the oil? I have no manual
What kind of oil should I buy? What does a oilchange costs?
Is there something what I have to do for a long engine life? (change spark-plugs etc) Has 85000 mls on the speedo.

Time based oil changes are not necessary, especially when you live in dry climate that doesn't trigger condensation. Oil in my motorhome is about 5 years old and I had the synthetic in my boat for 5 years since it was parked on the land.
Bear in mind that the same engine burns about double the fuel than it does in a pickup, so if don't stretch the mileage based intervals too much.
I think I change mine so often just for peace of mind, rather than an actual "need". I ask a lot of my truck and spend LOTS of time in dusty, off road environments. I guess I feel it's the least I can do, not like it's going to do any harm.
"0-60 takes 5 and a half seconds...and about 17 gallons of fuel...."
+1 on that. My theory is that nobody ever lost a motor due to the oil being too clean.
The truth is that oil quality plays small role in engine life. I am pretty sure any today's engine will run for over 100,000 miles even on cooking oil.
Years ago I worked with a guy who never changed oil in his Nissan truck and added oil only when the red light would stay for over a minute.
By the time I changed the job, he logged 140,000 miles still running perfect. That was in 1980's when not too many engines having oil change 3000 would last for 140k.
Contamination aside, modern oils changed too soon do damage the engine. Again the difference will be not noticeable for owners, but the chem pack and overdose of detergents in new oil is calculated for recommended intervals, so changing the oil at 1/2 of recommended interval is draining perfectly balanced oil and dumping excess of chemicals with a new one.
The OP might confirm it, but lot of cars in Europe run 40,000 km on oils.
Than how many of us care if the engine will last 800,000 miles, or only 750,000?
Ops this is a thread about gasser. Ignore my last numbers.
When you post completely ridiculous statements like the first one, it's quite easy to ignore pretty much everything you say.
Oil can go to crap with age especially dino oil. Only way is to do a UOA. Thing is for the cost of a UOA I could do a change with PP and an Fl820s oil filter. We are only talking 6 quarts of oil here. If I could get 5w-30 Motorcraft oil in 5 qt jugs readily I would probably use that.
