    High mileage
    By  JOE,  a  Verified Buyer  from  Virginia   on  April 04, 2024
    So far so good. Oil changed 800 miles ago with this high mileage formula. Engine ran quieter after the oil change. Main reason for switching to this was because of burning oil. Was burning a quart every 5k. This oil hasn’t been in the car long enough to determine if that will change. Gas mileage seemed to get 1mpg better through 2 tanks.

    Coyote 5.0 F-150 This saved me quoted $4,000
    By  DAN,  a  Verified Buyer  from  Kansas  on  April 04, 2024
    All Ford F-150 5.0 Owners with issues, Rough idle and dies at stop lights, sends multiple codes Timing, cam position sensor, VVT. After I took my 2016 F-150 165,000 miles, in for service, oil change, the check engine light came on and it started idling rough and dying at stop lights, when I talked to the mechanic he told me it was cam phasers and it would be cheaper to replace the engine $15,000. of course I got a second opinion, they said I needed to change the timing chain, and rebuild the heads $4,000. I decided to do some research of my own, found that many Ford F-150 owners had the same issue, many different tried fixes none worked, Changing the VVT solenoids seemed to work for some of them, so I purchased one of them so I could see how they work, long story short the VVT solenoid is piloted by oil. Oil in this engine is critical in the operation of the F-150s variable valve timing VVT, I looked back at the oil change records and they actually listed the brand and weight of oil they used in that last oil change Havoline 10W-30 and a Fram oil filter, that's when the problems started!!! So I decided to try an experiment. I drained 1-quart and added 1-quart of engine flush, ran engine for 5-mins, drained all the oil, installed a new oil filter from Amsoil, and filled with Amsoil high mileage oil, I noticed immediately the sound of the engine was so much smoother. the check engine light was still on, but it ran so much better, after about 50 miles of driving the check engine light went off, I've been driving it now for about 4-weeks 300 miles, no issues with rough idle and hasn't died at a single stop sign or stop light. Thank You Amsoil !!! saved Me an engine replacement and a whole lot of headaches!!!!

    Yes, I would recommend this to a friend.
