I generally change mine around the 80% mark on the computer. I trust the engineers that program the computer but would rather err a little bit to the safe side when an oil change is $20 and a new turbo could run in the thousands when labor is included.

I would assume that you must have an F150 3.5 ecoboost,as I can't see getting 3 gallons of oil and a filter for $20! It runs about $74 for oil and filter for our CTD.

I do have the Ecoboost and I use the 6qt box of oil from Walmart. You can get 6qts of a name brand synthetic oil for about $15.47 so it is about $20 by the time you add a filter. By far the least expensive way I know of to buy a good oil.

Chevron in a box.

My daughter went to an oil change place in San Antonio a while back and they charged they charged her about $65 to change oil in an Ecoboost. Their advertised special only included 4 qts of oil and they insisted that she had to have high mileage oil at an extra 2 or $3/qt in addition to gouging her on the two extra quarts. She only had 75,000 miles on the truck. I have to question the value of high mileage oil anyway but it is definitely not needed at 75,000 miles. And, as you can see from the oil in the link it is not even that expensive. An absolute ripoff! She was too far away for me to help but she did learn a good lesson about the way some businesses work.
