I wondered how newer vehicles were able to support longer intervals. I grew up on the 3,000 mile oil change. But how many of us are able to take advantage of the $19.95 oil change any more.
Trailer Trash2, how many quarts of oil did you old truck take?
One of the major reasons for longer durations besides improvements in oil and engines is the amount of oil in the crankcase. My truck uses 15 quarts of oil (almost 4 gallons), my car uses 11. If in the past a truck only used 6-9 quarts, this is almost double. Vehicles typically used 4 or 5 and for many cars it is far more. That means twice as much oil is available for lubrication as in the past. This contributes to longer oil change intervals.
Just something I read some time back.
And Phyllen, if you are ever in Southern California, stop by my stickhouse and I'll be glad to change your oil/filter. You buy the oil/filter and I'll provide free labor and disposal. How about that? I do my own oil changes now that the free maintenance is gone. I have all the tools and we have the same vehicle.
