There are many factors that will have an impact on the oil and likely make it lose properties quicker. Lets see a few:. So will a diesel pickup with Hell no. There is no magic calculator in which you input every variable and it gives you an accurate number of miles inbetween oil changes.
And since there is a lot of discussion lately on why manufacturers are constantly changing their recommendations, we also want to share our take on this trend. So the first thing is clear. Synthetic oils last longer and overall perform better.
But or even miles is pushing it way too much. BMW recommended miles or 24 months around … but then for all models and applying to older cars too, they changed to miles or 12 months. Why that change of mind? A high rate of failure of mechanical parts at low mileage , essentially. Car manufacturers are responsible for as long as the car is on warranty. Short-term problems are their problems. But long-term problems are their profit. So basically once they saw that their oil change schedule was costing them a lot of money, they decided to shorten it.
Same with break-in oil changes. It is costly for manufacturers to do it after miles. They will refuse to conduct it, literally. But that is the moment in which you should do it. But here is the trick to that. Most systems GM, Ford, PSA to name a few calculate the oil life based on data collected from different engine sensors. It is pure software. Pretty much the same. There is no sensor actually in your oil pan. So with no actual readings being taken straight from the oil, you cannot know precisely what is going on.
