Oil Change interval based on time
Hi everyone. I did a search for oil changes based on time and not mileage and didn't find much so I thought I'd ask. I'd like to get some opinions on how often to get an oil change based on time. ...

Consumer Reports debunked the 3K oil change 40+ years ago using NYC Checker Cabs... I went to 5K back then (easy to track by looking at the odometer). 30+ years ago oil testing let me increase from 100 hours (Cat recommend hours) to 250 hours on my Cat heavy equipment. Even at 250 hours the oil was still useable but 250 was easier to keep track of... just look at the hour meters. Oils have come a long ways in 30 years, not even including synthetics.
A good filter does not go bad in a year or five.:S If you believe they go bad then just put on a new filter each year.
All of this applies to Diesel engines where it's gallons of oil, not quarts. If I had a gas MH I would change the oil ever 5K miles reguardless of time. Easy to keep track of when it's needed.
Just one more for the extended oil life/service intervals. Back in the early Amsoil Days I started to go to 25K and synthetics in the over the road trucks and 500 hours on the equipment - in 25 years and Millions of miles/hours of service we never had an engine or pump failure.
When the oil was changed we then used it for heat in the shop in the winter.
Low oil will kill an engine, but today's synthetics Last a long time.
On a totally different subject - Low air pressure is the cause for most tire failure not age.
JMHO,
