Re: Oil Change - Hours vs. Miles
I agree with the posters that the Blackstone analysis is the best indicator of oil and engine condition, but it is fairly expensive and will vary depending on usage.
Let me propose an alternative solution to the mileage/hour-meter debate. I go by fuel consuption. On summer fuel I plan to change my oil at around 18 tanks of fuel. On winter blend, 20 tanks. So, if I do a lot of low speed highway mileage, the fuel usage based change puts me at ~5000 miles. If I am doing a lot of high GCVW towing at high speeds, thus working the engine hard, the fuel usage method will tell me to change the oil ~3500 miles or a little less. It works really well for when you do mixed driving. Tracking is fairly easy. Just a notepad and pencil.
This system is not perfect, but it does account for changes in usage and idle time. As my truck ages, I continue to monitor my oil condition with Blackstone about every third or forth oil change. FYI, my Blackstone results have been excellent.
What do you guys think?
