Should change the filter at least 2 times a year. Remeber the fuel is always being pasted thru the filter. But if you get to it once a year that is better then not doing it.
The engine oil should be changed every 3000-5000 miles
Every 2000 miles
Follow the recommendations in your owners manual or change it every 5,000 miles.
every 10,000 miles
Probably every 5000 miles. Or 6 months.
It has a permanent filer that is changed when the fuel pump is replaced.
look in your owners manual but usually at 100,000 anymore.
AS dirty as todays gas is you should change it every other oil change and that will also make the electric fuel pump LAST LONGER. Another answer: I recommend you change it every 36,000 miles.
It is best to change the oil after every 6000 miles. The most important thing is to follow the recommendations for your car.
Unless you work the truck real hard then it should be changed about every 40.000 miles. I believe your truck has a transmission filter on the bottom of it and I would change that every other oil change. I think it is a screew on filter.
It doesnt matter what car you drive. Every 3000 miles or 3 months whichever comes first.
