How often do you change oil in your TV?

[comfun1]

I have a 2005 GMC 2500 6.0 l that I use mostly to tow my camper with. I changed oil in the spring and since then I have driven about 3,500 miles up and over the Rocky Mountains and back. I am getting ready for another trip to the rockies this time it will be about a 2,000 mile round trip. I use Mobil 1 synthetic. My friend says towing up over the mountains is extreme duty and I should change oil before this next trip. I told him I thought the synthetic oil should last longer. Now I'm not so sure. Wondering what everyone else is doing?

I would change the oil. Your truck should have a oil life moniter on it. What percentage is it at?? I do full synthetic and change every 4K

Oil does not wear out just gets dirty. Although I do change at 5000 miles I know people that never change oil just change the filter about 4000 miles. They also keep vehicles 10 to 15 years. To me extreme duty on your engine is cranking it drive across town shut it down cool off the do the same thing that evening. With oil test you will find out this causes acid build up that is more harmful to the engine than crossing the Rocky Mountains a few times.

Change mine once a year in the Spring. Really only use the truck for towing and a few trips out of town to keep it charged. 2011 and has just over 6700 miles on it.

Every 4-4500 miles with M1. An oil change is cheaper than a motor and pushing the factory programmed OLM. Synthetic is better at lubricating, but it still breaks down like standard oil, it just takes longer. I would change the oil before the next trip!

Every 5000 miles with regular 15w40 Rotella-T dinasour juice.
I occasionally send samples to Blackstone Labs and they always come back telling me I could go longer intervals if I wanted,

At 211,000 on my '01 PSD there have been no interal engine issues or oil related issues. Original turbo, injectors, HPOP, etc.

Between every 3k to 5k. I have a Ford 6.0 so I have to keep the oil fresh.

I change mine at 5K the oil life monitor still shows i have 50 to 60% left

I change mine about every 5k or 1 year. With that said it has 3k on it now, but I am going on a 3-4k trip and will change it before I leave and then shortly after I get back. Just my personal preference.

Do mine by the owners manual, usually there is a severe duty and standard duty schedule. I go with severe duty as I live on a dirt country road. My trucks have all gone to the selling dealer their whole life so I never worry about it.

I have a 2013 GMC 2500 6.0 L, and the oil life monitor sets it at 7,500 miles, so far I've only changed it once right at that mark. I have no plans to change it any sooner. This is what warranties are for haha.

I also rotate the tires at the same time (I only do 10K per year btw)

My 2014 F150 also ran synthentic and I never changed it before 5K miles on that one. Traded it with 105K miles on it, never had an engine issue and it didn't burn up any oil between changes, fwiw.

I also change the oil in all of my vehicles every 5000 miles. Easy to keep up with via the odometer.....when it rolls around to 5 or 10 thousand, I know it is time.

Every 5K or a little sooner if a long trip is planed. Also do the rear diff every 10K and the trans once a year. Dealer does the trans, no dip stick and is a sealed unit.

[RSchleder]

I normally go 5k miles as a guide, or at least once a year.

OK, so I finished changing the oil and filter and when I get done with this post I am going back out and will crawl under and grease the truck. I suppose the grease interval may as well be the same as the oil change interval? I don't remember my f150 having many if any grease fittings but this gmc is loaded with them.

Rotella t6 every 5-7k ...all of my blackstone samples say I could prob go a lot longer. At 22k on it its had 3 oil changes and a new set of fuel filters....its mostly parked in the garage these days as i dont drive it as much so ill just go to once a year changes since I wont hit 7k ...i cant imagine even if I was clocking a lot of mileage I would ever go over 7 max....on the flip side I had an 88gmc that was my beater. ..it burned oil (quart a month)...just added oil...never changed it or the filter...it was still running good 8 yrs later when the block and tranny were swapped!!..lol..and that was on cheap ol walmart oil...
