Three important staements HELP OIL CHANGE

[wwr]

one tech says change every 3000 miles

one tech says the sensor is more accurate than using time (months)

one says 5000 miles or wait til sensor says change

What is the answer?

I've heard that the sensor is much more accurate than any standard time but that it should be changed once a year at a minimum. In addition I've been told that any earlier than that is just a waste of oil.

Just proves there are many different opinions on the subject.

I like to do mine every 3K with mobil one or if I am using amsoil every 5K. If you want to go with the Oil Life monitor great, I wouldn't go longer then a year time wise. This is my opinion.. some engineer will tell us different some tech with say this it's all blah blah blah... if it's DIRTY I would change it ASAP. If not then no longer then..... a year at most while monitoring the oil life and I would still stick to 3K or 5K intervals and the most frequent.

The weak link here is not the oil....it's the oil FILTER, but since you have to replace the filter, then, well....{obvious statement here}. Sensor works just fine as a guess. I just go by this: if I'm driving it harder than usual, than yes I'll change it sooner (5,000) but generally, the sensor is working just fine!

It never hurts to change your oil early... but it does if you let it go too long. What's it gonna cost you to do it early?? 50$ additional a year?? Ask your self one question: "Do you feel lucky punk? Well do ya?"

I believe that c4c5 specialist has posted on this before. If I remember correctly, he says to use the oil change monitor system in the driver information center.


I think that system uses a set of formulas to determine when to change the oil. It does not directly monitor the condition of the oil. I thought that it kept track of things like oil temp, number of engine revolutions, full throttle accelerations, etc, etc to estimate oil condition. Is this correct?

I'm with bounty hunter here - the oil filter is the weak link. I change the oil filter every 3-4k and the oil every 10-12k or every 3rd filter.

It works for me - I've been doing the same on my 92 for years and years. Back in 2003 with 103K on the LT1 I had the motor upgraded with heads and cam so the mechanic pulled the motor to replace the bearing and rings. Everything was perfect inside. All bearing surfaces were within standard specs and the cylinders did not have any ridges at the top. The mechanic burnished the cylinder walls and installed new standard rings and bearings. I was pleased to say the least.

My 03 AE and my 04 CTS-V get the same service as my 92 continues to get.

I do the same as I've done with all of the motorcycles that I've had. Now, let me preface this by saying that my bikes and Vettes all go into winter storage.

I change the oil and filter every 3000 miles. I also change it just prior to putting it away for the winter and again just before I put it back on the road in the spring. I also change the rear diff fluid, etc.

Overkill? Maybe,but I've never had a problem in 35 years due to any fluids.

I go by what the manual says!

 

[Tuna]

Oil changes are like asking favorite color and which wax to use. Doesn't seem to matter as long as what you do does not compromise the motor. What I do does not compromise the motor and it saves recycling 5-6 quarts of oil every 3000 miles.

Stay away from the tech that told you that big one. There is no "oil life sensor" that analyzes the oil. Only a computer that measures RPM's, temp. & time and compaires that to a look up table.

that computer is probably what the tech meant

 

[The Drakester]

I change the oil every 6 months. I average less than 3K miles a year.

 

[Tomrw]

I change my oil , Mobil 1, every 5000 miles. I have always been a believer in the 3000-5000 mile range. I usually get rid of my cars with 150,000+ mile and have never had a engine problem. Changing the oil is just smart.
That's my 2 cents.

[OLDCHEV]

I use 10W-30 Mobil 1 in all my vehicles (GM vehicles). I change the oil every 10,000 miles with an oil filter change at 5,000. I only use Mobil 1 filters or K & N. I recently had to change a leaky valve cover gasket on one of them and the valve train looked just like new, there was no sludge anywhere. The key is to prefill the filter completely with oil (no dry starts).

Hi wwr -

I work for a company that manufactures engines and big yellow bull-dozers in the great cornfield.

We have some of the world's premier metallurgists and tribologists working for us.

Our engines can go 1 million miles without needing a rebuild if properly maintained.

The experts that build (and warrant) these engines recommend oil changes based on chemical analysis of the oil. This is because some of these engines take a whole lot of oil for a change (compared to our measly 6.5 quarts), which makes it cost prohibitive to "over-maintnenance" them.

Now, you could go up to 12k miles between oil changes if you go by the GM book and the DIC. You could also drive with your feet if you wanted to, but that doesn't mean it's a good idea.

I personally LOVE to get the vette up in the air an drain the oil, and check out all the neat stuff under the car. As fine as a C5 looks, the best stuff is underneath IMO. I just have some fun with the car while maintaining it.

I have had some prognosticators tell me that I change the oil way too much when I drain Mobil 1 out at 3500 miles, and that I am "wasting perfectly good oil". I have as yet to have one of these "experts" agree to use my perfectly good drained oil in their Corvette, though.

In short - to me it's therapy to change the oil, regardless of the minimum manitenance schedule for an oil change.

best regards -

I'll change it every 2500-3000 miles with Mobil one and DUraguard Gold filter. Some may say its a "waste of oil" but after paying the prices we pay for the cars, I can justify a few extra oil change dollars. Trying to be "practical" when owning a Corvette is an exersize in futility!!! :L

 

[Steve Calvin]

Agree totally BLUBYU. Like my Dad always used to say... "gas and oil are the cheapest things you'll do to a car, why take chances".

Works for me! Especially with a fairly expensive car. Hell, the insurance costs $400/year anyhow. If a hundred bucks or so is gonna break you up then you shouldn't be driving it in the first place.

 

[warren s]

Every 5000 here, I actaully like the "oil change morning routine" I try to also do my Pontiac and my friends C5 while i am dirty already.


ONE thing I was told years ago before synth oil like Mobil 1 was popular, was that over changing the oil and filter is bad because you are running the motor with no pressure for a few seconds before the oil gets picked up and circulated through the engine every time you do an oil change. You want to avoid that as much as possible. Mobil 1 leaves enough of a film on the bearing surfaces that it would take a few minutes to really do the damage that would occur in seconds with dino oil.

 

[BLUBYU]

You can avoid the dry start up by fillin gthe oil filter with oil before you put it on.

I been doing that for years ... it works too .. you have oil pressure right away
