They do that because the companies know people like to fuck around. You'll change it half as often as recommended, so they recommend you change it twice as often.TG <-
I've always heard that "recommended" oil change miles / dates were way exaggerated.
That is for old engines from the 80s and back.recommended is 3000miles or 3 months, which ever comes first.
Oil and filter get dirty from the breakdown of engine parts and the breakdown of the oil from movement and temperature cycling.
No, you do not need yearly oil changes if you only drive 1000 mi a year.
It's based more on Revolutions than anything else.
Oil has a shelf life, but it's probably a long time.
I looked around online to back up my statement and most places recommend yearly on low mileage vehicles.
It doesn't state the reason, but one reason could be to generate revenue.
You're right, the engine mfgs don't have anything to gain, but the automakers do.Car and engine manufacturers have no revenue stake in oil. They do this to prevent wear and excess warranty claims so it has ACTUAL merit. Oil has a shelf life, exposed oil (not sealed in a container) is far less than people think it is.
You're right, the engine mfgs don't have anything to gain, but the automakers do.
Dealerships and service centers have huge incentive to give regular oil changes.
Each oil change is revenue and the opportunity to sell more goods and services.
Why do you think the 3 months / 3000 miles scam is still present?
I do once a year on reg or syn and I am not one to change my oil early. Less than $20 and good to flush it at least yearly. That and a good time to check out the tires (they also go bad by age), belts, hoses, etc...
If driven that little I would use reg and just change yearly. My truck and grandmothers car falls into that.
You should be inspecting your tires weekly...not annually.
As for oil, I'd change it at least once a year even if the vehicle had less than 1000 miles since the last oil change.

True but most don't even check anything unless its making noise or not working anymore. And even then they say "i'll get to it..." :awe:
As you are rolling your Exploder over and over, cart-wheeling through the trees, you think, "Gee, maybe I should have checked those tire pressures." :awe:
