Home Forums Gear Hunting Trucks and Four-Wheel Drives why change oil once a year?

I have seen on several web sites for oil change intravals of 10000-25000 (OR) once a year. Why would you change your oil that is recommended for 25000 miles at 15000 just because it has been in there for a year?

I guess same reason some people (for whatever reason) still swear by every 3000 miles. What a waste of money and oil.

Depending on location changes in temperature create condensation that accumulates in vehicle

On cool days,watch a vehicle going down the road after 1st starting. Notice that dribble of water coming out of the tail pipe. Then figure out where that water comes from.
In additon all these 15-20,000 mile fans probably do not change the air filter still at 10-15K intervals as recommded.Some of that dust gets in the oil that filters do not all filter out.

These fancy oils, although they do not break down,they still get contaminated. Water and dirt are the cupprits. But hey, it's your$40-$50 K vehicle. Save that $50 for an oil change.Once a year for 20 years will save you a whopping $1000,if your engine lasts that long.

That makes sense. I just couldn't understand why you should change oil that had hardly any miles because its year was up like an expiration date. I can see moisture being the reason, dust not so much as I keep filters changed regularly.

Condensation as a byproduct of combustion and temperature changes from heat cycling. Said moisture is very acidic and doesn't really do your engine any good if left in there for long periods of time.

Well I've been doing that on my vehicles...

a 94, so that is 21 years old...

a 93, so that is 22 years old...

an 88, so that is 27 years old...

and yeah, the engines have lasted that long and don't have sludge issues, as I replace valve cover gaskets every 50K, if they don't need them sooner...

The condensation is not good, but if you drive your vehicle regularly for any appreciable amount of time it will burn all that condensation out and it's not really an issue. If your vehicle sits for long periods of time or only gets driven for really short trips where it doesn't get a chance to reach operating temperature then it becomes more of an issue.

My truck does sit for long periods of time, 09 but only has 25K on it. But when I do drive it it is usually not short trips and is usually highway miles pulling my jon boat to a hopeful honey hole.

I'll be lucky to get 6000 miles on my truck this year. Down from 40K a year average when working.

it depends more on how you drive your truck than how long or how many miles. if you use your rig for short hops around town or in dusty/dirty conditions, more frequent oil changes are called for. if you get the motor up to operating temps for long periods of time and it sees mostly highway miles, extended oil changes may be fine. the heat will boil the condensation out of the crankcase.

TFF!!!

Why's that so Friggin Funny Scheiss4Brains?

you probably just take your car to the shop, as putting gas in the tank and the key in the ignition is about the limit of your automotive knowledge...

betcha I get a lot more miles and reliability out of vehicles that you ever have...

so laugh your ass off and even piss in your pants from it...
that would seem par for the course for you...

you really like to think you are something special don't ya..
cause mommy told ya you were? yeah that's probably it..

You're a bullshit filled floppy titted gasbag.

I run rigs harder than you can ever dream of, and have NEVER needed to replace valve cover gaskets as a routine maintenance item. Even under severe duty schedules.. Nor has ANYONE I've ever known.

You're just in love with your own lies and bullshit, and everyone knows it.

YOu really are a SCREWed in the head A/HOLe....

"bullshit filled Floppy titted Gasbag?".. you been holding onto that one, for just this occasion since the 3rd grade? sounds like something a juvenile would come up with, and think it would insult someone... coming from you... well, what could one expect...

and yeah, I pull valve covers off every 50K... and replace them, as I inspect what it looks like under there...

ya think I said that to attempt to impress anyone? on the friggin internet no less? you really are a friggin MORON, even by Callifornia standards....

Here's something even funnier then, I also pull the brake pads out and replace them every 50K... Life time warranty, so it doesn't cost anything but my time anyway...

Here's another laugh, I even change the tranny fluid in an automatic every 20K....and in a manual, to include the rear end and front diff on the 4 WD every 50K also...change the final drive fluid in the automatics every 50 K also... and change spark plugs, rotor and distributor caps every 50K...

and I don't brag that I beat the crap out of my vehicles...such as you do...Congrats are in order?

So Laugh Away Schitt4Brains....I sure hope I get to meet you face to face someday, to see if you are really as big of a dumbass in person as you like to play on line...

Put that in your TFF note book...then you can review it at your convenience...

Have a nice day Schitt4Brains... and have someone pull that corn cob out of your AHole... maybe you'll not be such a little bitch all the friggin time..

I've been getting 75K out of my valve cover gaskets.

Battery at the same time?

you are really living on the edge. my goodness, what if one were to seep a little bit?

This thread is funnier than fuuck!

I put new air-make that fresh-in my tires wither they need it or not.
