Mobil 1 has a fully synthetic motor oil that lasts 15,000 miles! Of course if you have an oil change light, you'll have to learn how to reset it so it thinks the oil has been changed. But let's break things down over the long run.

Goodyear charges 24.99 plus oil disposal fee and state taxes for a regular oil change, then they recommmend 3k intervals. That's a lot of money over a 15k period.

Leda's 03 Toyota Camry recommends regular oil at 7k intervals, but I would not trust that with regular motor oil. She uses synthetic at 7k intervals, still saving but not as much as the 15k stuff.

Vicky's Honda civic has a sensor for 3k intervals, but I know how to override it. At 7k intervals I change the filter, but do not change the oil until 15k. Anybody can change a filter at home, just make sure you have a drip pan as a small amount of oil is still in the filter.

Do the math, it pays to spend a lil bit more for a performance synthetic and filters instead of doing the full filter and oil changes at 3k or 7k intervals.

Hey, a dollar saved is a dollar saved, it all adds up in the long run.

Still use conventional Castrol 10W-30, and change roughly every 5000 miles. DOn't pay anyone to do it, being as my Dad lives in the woods, we simply change ourselves and save the old motor oil for varrious uses (makes a darn good waterproofer/anti-termite treatment for stuff like treestands).

I pay about about $18 an oil change.

I have 2 Dodge pickups that have 12k change intervals. I usually do it at 10k or once a year whichever comes 1st.

When the bearings in the engine finnally grind to a screaching halt.

I change oil, plugs, filters (all of 'em), every 3000 miles or so. 154,000 miles later and Ive never had so much as a knock in the motor. Never had to replace any major parts.

When the oil light flickers as I sharply turn a corner....

Seriously...every 3-4 months as long as the weather's good....tomorrow will be -10 F...won't be changing any oil..enticing squirrels with peanuts so my granddaughter's entertained as she watches through the windows..I'll do that...

Car's still not too old yet, so it's still roughly 3000 miles and I get the oil changed.

I did that with a previous car and it, in other hands, is still running after close to 200k miles.

I neglected frequent and regular oil changes with an even earlier car and it went kaput after around five or so years.

I use Mobil One. I can go 20,000 miles between oil changes.

<Say, what's that noise?>

Must be the warp injector coils pulsing out of sync with harmonics of the field stabilization matrix generator. I recommend you get genuine Spican flame oil with 6.75% deuterium enrichment (sounds like the stuff in some Northern Chinese or Mexican cooking... ) and lube the flux initiation damper blocks.

Every three months or 3,000 miles whichever comes first. With a six mile commute I rarely even get close to 3,000 miles, I figure the body will fall off before the engine is ready to pack it in.

Um, is this one of those 'if train A leaves the station at 7:45 travelling west at 45 miles an hour, and train B leaves a seperate station at 8:02 heading east at 52 miles an hour, when will they collide?' questions?

Jack Morris · « **Reply #11 on:** February 24, 2006, 06:51:21 am »

I would need to know the distance from station A to station B, right? I know, I suck at math, that was and is my weakest subject in education.

Don't let anyone tell you that you can let your car go 15,000 miles without an oil change. Yes, the oil will retain its properties that long, but pollutants WILL get into the oil, the filter won't last that long, and you'll be increasing the wear on your engine.

If you drive nothing but freeway miles (and I don't mean California, bumper-to-bumper freeway), you can go 7500, but I don't recommend it. 3 months or 3,000 miles will double the life of your engine.

Never,the cars i use got a special oil filter.This filter nearly voids the need to make oil changes within a motor liftime.
http://www.trabold.de/
I know its in German but there is a nice picture of it on the front page.

E_Look · « **Reply #14 on:** February 24, 2006, 11:45:05 am »

Kehakoul, I'm sure the filter is great for trapping all metal particulates and even other particulates from your oil.

But the reason to change oil is not just the solid gritty junk in it. Given today's engines, the oil is more harshly treated than in the past and it chemically breaks down. So, it no longer lubricates nearly as well as when the oil was newer.

I suppose you won't have to change the filter ever, but the oil has to be periodically.

The Postman · « **Reply #15 on:** February 24, 2006, 04:52:34 pm »

I forgot to mention that after I change the oil, I dump it right back into the fuel tank.

Jack Morris · « **Reply #16 on:** February 24, 2006, 06:20:06 pm »

I think you might want to brush up on your German, like E-look said, and any auto parts or auto tech people can tell you, oil has chemicals added that do break down, that is why we try to recycle oil, because it can be filtered and separated and then have new chemicals added.

The filter is permanent from what they are saying, not the oil. That doohickey can cool oil all it wants, it doesn't matter in the combustion chamber where the pistons are going warp speed and there is a LOT of heat in that mo-fo.

Usual oil change against Trabold Oelfeinstfiltersystem (10er) usual oil change price for 1 l oil (5W-40): €Preis for standard filters: €Oelinhalt the engine: litre oil change interval for normal oil change: kmStundenlohn for oil changes: more €Zeitdauer for normal oil change: min TRABOLD OelfeinstfiltersystemEinmalige micro-filter acquisition: €Erstmontage: €Preis for micro-filter cartridge: €Wechselintervall the micro-filter cartridge: kmStundenlohn for micro-filter changes: more €Zeitdauer for micro-filter changes min for km the acquisition of the high speed filter is one of the most interesting investments. The filter has one a life long. It lands not on the scrap iron, but from vehicle to vehicle again and again converted after the 5ten no longer made oil change that the Trabold high speed filter already amortized.

Also, where is their guarantee IF the engine does seize up due to oil breakdown beyond the manufacturer's specs or an oil company's specs? At least I have a receipt for Mobil 1 sythetic 15,000 mile oil and a filter, and will document the changing of the filter too. They have a clearly printed guarantee. That German doohickey does not, so am I to trust what could be auto parts "snake oil?"

We are using Mobil Synthetic (Mobil 1) in both cars and the piston-plane (AV1). They follow the same oil change schedule. Oil is replaced every 200hrs. The oil filter(s) are replaced every 100 hours. The hourmeter is the first accessory mounted in the car(s). The engine oil only cares about operational hours. The engine can be running for 200hrs and the car travel 15000 miles, or the car might not move anywhere at all. On my commercial van ('64 International 598k mi); it has the filter replaced every 50 hours due to blow by. Oil is tested every time the filter is changed (http://www.avlab.com/analysis/login/default.asp).

The commercial oil filter listed can work, but without test results..? I wonder why you do not see this type of system used on commercial vehicles?

Jack Morris · « **Reply #18 on:** February 24, 2006, 07:10:50 pm »

Or being in high demand for that matter, at least K&N gives guaranteed results on their products.

No lectures needed,Elook, its exactly the other way arround,..you got to change the filter after a few years.
With a modern motor oil the need to change it is virtually wiped out.

Second this is actually a oil filter/ cooler unit and more its connected to the motor and gear,you use two ,one for the gear the other for the motor.
Its a German inventon that faced harsh opposition from the Auto industry over here in Germany and most important from the oil industry etc.. guess why??

Fact is its is fielded at the moment in many German towns for public service cars to anihilate the need to feed the oil scammers further.
And it works as i said, regardless what you guys might think!:)

Have a nice day.
