Yes I agree with you happyfer22, Preventive Care is the best thing for a vehicle. This can be said for anything, lawnmower, tool and the like.
It may be poor preventative care in *your* opinion, but it is not poor preventative care in the opinions of the mechanical engineers that work for Ford and the petrochemical engineers from oil companies that they collaborate with. That is the care recommended by Ford. The recommendations are essentially the same if you own a Toyota. So my question is, are you an engineer that has done research in the area of engine lubrication? If not, what insights do you feel that you have, that the thousands of automotive engineers around the world do not have?
The oil life algorithm that is programmed into every modern vehicle comes from oil life analysis by the mechanical engineers at auto manufacturers in conjunction with pethrochemical engineers at oil companies, spread over dozens of engines, run at varying loads and temperatures, for prolonged periods of time, and then serially analyzed, at an expense of hundreds of thousands of dollars. That provides a superior assessment compared to an end user with no scientific background seeing a single read out of their engine oil and then coming to their own conclusions about what that data means. There is a high probability that the end user will interpret the data completely differently than an actual automotive engineer would.
Yes, I understand how it was designed. However, that doesn't change the accuracy of my statement: an oil analysis provides more insight to that particular engine. In fact, the oil life algorithm provides ZERO insight to that particular engine, other than an oil life percentage. The ability of the owner to intake that data and understand the insight is beside the point. I can read an oil analysis and have more insight of the operating parameters of an engine and the condition of the oil than the percentage of life remaining shown by an algorithm every time.
Exactly. I'll trust hard data and tribologists over manufacturer recommendations.
