    I have this weird auto allowance that requires me to have a newer vehicle. It cannot be more than 2 model years old.

    My Silverado is smoking like crazy on start up. I add oil but do not want to spend money on oil changes that will not benefit me. I put on about 25k miles a year. At 75k the truck will be traded in.

    I figure one change a year would get me by.

    At what mileage would a engine fail because of no oil change?

    Depends, but I always go by what the F150 oil monitor computer says which is around 10,000 miles

    I change every 5k whether it needs it or not, along with tire rotation. Have went 15k on the Mobil1, with no adverse effects. If you are adding oil often (quart a week or two), I'd just keep running it and change the filter every 6 months. Oil changes shouldn't be more than $50, if you do it yourself. Cheaper if you run cheap oil. If it's using and smoking, I'd buy the cheapest I could find and change it. At 75k, if it is smoking, it sounds like you have missed quite a few oil changes already.

    I've got an '06 Ram with 4.7L and 180,000 miles this week. I've been changing the oil and filter every 15-20K miles, since new. I run mobile 1 full synthetic 10w20. No smoke, no oil consumption, no noises. 20mpg.

    I've got nearly 100K miles towing boats in the Appalachian Mountains on this truck as well.

    Every 3 or 5000 miles. With good old castrol 10w 30. Hope y'all know most oil filters are only good for 5000 miles.

    I heard of Ford EcoBoost's causing the same smoke start-up issue...

    Does your Silverado have the Active Fuel Management option? If so - see if you can turn it off and then see if it stops smoking at startup...

    Went a couple of years between oil changes a few times with my 2000 Olds Alero "Extreme". It had a minor oil leak, so I'd fill with the cheapest stuff I could find when the oil light came one and then just let nature take its course. Finally let the car die at about 260K when I decided not to fix the water pump and let it basically explode from overheating. On the bright side, I got $300 for scrapping it, more than it was worth on KBB. I miss that car!

    Same with my Canyon and wife's Acadia.. We both usually get about 9 months out of it.

    My Ford F150, 5.0 V8 came with an extended service plan which included 7,500 mile changes with synthetic blend oil. That is absolutely the longest miles I feel comfortable with.
    When the service plan is over, I will change @ 5,000 with full synthetic. I plan to keep the truck a long time.
    On engines with turbo's I would not go longer that 5,000 and run full synthetic.
