Is anybody using the Moble 1 the 15,000 EXTENDED Syn Oil ?
(1) If so, How long are you let it go before changing it ?
(2) Mine is about 8,000 miles now.....should I stay with it longer or change it now?
(3) Note: I'm also using the FRAM extented oil filter (black filter)..
(4) Are ther better filters out there for this type of oil?
TP

Many who work on cars call FRAM oil filters the orange can of death. Wix filters are much better built.

If you're going to use the Mobil 1 Syn, then you should of used their extended performance filter....

I couldn't sleep at night knowing I had dirty oil in my motor for 10,000 miles or more. One of the main reasons for changing the oil is to remove the contaminants that can turn to sludge inside the motor. The filter doesn't remove them since they are too fine.

1) I go 4k MAX on any synthetic oil. Mobile 1 in the 97, Rotella T6 in the GTI.
2) Change it
3) Fram = crap. Their product quality has suffered big time from the early years of the company (some blame it on Honeywell's move to make products cheaper and overlook overall quality. i.e. something they are now doing with Garrett Turbos). Many of the ol' timers still think that Fram quality is what it used to be 20,30,40 years ago, but it simply is not, they just have brand loyalty and will swear by it till the day they die Just ask Kyle who works at Advance Auto Parts. People also have a big name association with Fram since they see it in commercials and such thus they are familiar with the name and think that it much be a good filter.
The number of pleats and thus overall surface area of the filtering material is much smaller than other filters even other cheap filters like Puralators.

4) As Rick said, Mobil 1 filters are good and as Drew said Wix are also great. If money is an issue, Puralators originals and PureOnes are a good cheap alternative. Just stay away from Fram and especially the one they make which has some "High mile oil additive" crap inside the filter. Even some chain store brands are just rebadged filters made by those who do produce a quality filter. Look at the links I posted for more info on these.

Oil isn't just about keeping particles out of the engine. It's also about viscosity and shearing, things extended oils and synthetics try to battle. One of the main things that breaks down an oil is fuel which leaks past the rings and thus lowers the viscosity. Also as Don said, other contaminates and even moisture in the oil (if you take short trips very often) can cause the oil to not be as effective and leave deposits. A filter and an extended life oil can't stop fuel blow by and can't compensate for it's existence in the oil. Fun test. Try to ignite new oil. Can't be done. Now throw a match on your old oil. Nice fireball.

agreed fram = crap. I use rotella t6 in my car and change it every 5k miles. My dad changes his currently every 10k (using rotella t6). Throw a micron oil filter on your car and do like the germans and change your oil every 40-60k miles! Send in a 6oz sample of oil every 10-15k miles and run it till they say change it!

Then I guess I better change mine this week end,
Thanks for the input

I use a Bosch filter and Mobil oil in my Escort. Change it every 6000 miles with a 3000 mile filter change.

I use the napa gold filters and schafers synthetic which if i recall is good for 6 thousand miles but i change around 5. I get it all at price so its under 20$ for oil and filter.

Never go beyond 4k in what car with what filter setup? Just cause the car sits you don't get tha tmuch oil in it and if you drive it and get it to NOT when you do drive the water boils out of the oil anyhow. Nobody believes oil can go big miles, it's really kinda irritating. I change mine at 5k and when I send it in for testing the oil still has 65 percent life left and the metal/soot particulates are still within reason.

when oil goes to 80bucks a gallon I'm sure people will stop being so wasteful. Then again who am I kidding I drive so many freaking miles in a month I still waste more natural resources than the majority of you and I consider myself less wasteful then most haha.

open up a filter even a good one at 4,000 miles and then tell me you can still use it lol the filter is the only reason i say change the oil. as at least with the 3800 there is no way to change the filter wile keeping the oil in the engine unless you turn it upside down.

now if you had a remote oil filter where you could just change the filter with out loosing any oil then yes run the oil to 9,000miles no problem mpst diesle with remote secondary oil filtration have gone 15,000 on oil no problem wile changing the oil filter ever 4,000 miles

There's usually always oil loss when you change the filter only on most engines, you just gotta do it fast. I would put a pan under it to catch the oil then dump it back in the motor. You'll always have to add oil anyway since the filter holds a fair amount.

with how dirty my catch pans are at work and at home i am better off just putting fresh in if i am going though that much hassle lol

i also use regualr old dino juice i figure with one car having 220,000 miles and the other with 196,000 using the sysnthetic witht eh added cleaners is just asking for leaks beuase it will brak up all the dirt that is holsing the gasket together lol

Yep that's true, dirt fills the cracks in the seals and synthetic oil washes it away since it's high in solvency. I put it my daughter's 92 Lumina at 90K and after 150K no leaks at all. It must have good seals which is surprising for a 20 yr old car.

It can't be a police car since it doesn't say POLICE on it.

For anybody who plans on using extended oil change intervals, I'd recommend using a fleece/synthetic oil filter instead of paper. The paper filters can break down over extended use. I don't know exactly how long it takes for them to break down, but the cases I've seen have been after 10k miles.

Here's a link that lists the material of many common types of filters (scroll down to read about each filter): http://minimopar.knizefamily.net/oilfil ... rence.html

I personally use plain-Joe Mobil1 Full Synthetic High Mileage 5W30. Change out the oil and filter ever 4k, 5k tops. I also check and add oil as needed with each fuel up at the gas station, which ever so rarely happens if I'm low.

_________________

My last oil change I used the mobile 1 extended with their extended filter. I love it. I changed it at 10k and plan on going a bit further this time. It was not that dirty looking, and dripped real nice just like it was new.

Only problem with my car is the v8 likes to magically dissapear oil. I have to put a quart in about every 4-6k miles. No idea where it goes, the oil change does not look burnt at all either.

When I have the extra money I'm going to change it at 15k like they say and have it sent out to one of those testing facilities.

I personally have never and will never change my oil every 3 or 4 k especially on synthetic. Our cavalier made it 120k miles with never an engine problem and never changed before 6k on fill synth. (got rid of it just cause the tranny died) Blazer made it 145k running perfectly same thing.
Best example was my 04 hyundai accent that I ran the crap out of. Full synthetic never changed before 10k. I drove that thing like it was running from the cops at all times. Tranny and engine made it 175k miles (alot of back and forth to pittsburgh) with the only repairs needes where hubs. I only traded it because I found my last gp at a great price.

I already put 35k miles on the GXP with the original mobile 1 with oil changes between 7-8k miles. And yes I reset the oil moniter halfway though. I don't think mine works right. The place I get it changed at they allways think I'm tricking them by replacing my oil before I go in lol.
