I recently switched over to Mobil One Extended Performance 5-30. My goal is to run with 10,000 mile oil change intervals. The oil now is a dark transparent amber and I am at about 6000 miles.
How about you? Tell me you oil make and OCI.
Thanks...
I have been changing my Mobil 1 every 10k miles in 3 cars. All from the second oil change of the engines life. A toyota 4x4 with 287k miles on it, and Chevy lumina 3.1l with around 220k on it, and now the cavalier which has about 28k on it. I plan to change the cavaliers oil every 15k instead of 10k, because of the new formula.
The color of the motor oil does not relate to the life of the oil.
The key to a long and safe oil change interval is to make sure that you have a clean, well sealed Engine Air Filter cleaner. Paper filters much better then cotton guaze or foam, so dont be fooled.
For tests on oil life, air filter and oil filter relation, and secific application testing, check out this website:
http://theoildrop.server101.com/cgi/ultimatebb.cgi
This site is a forum that is dedicated to engine oils and oil filters/air filters, and they do many tests on engine oil life and engine oil related topics.
The fact is that you can safely run Mobil 1 Super Syn Exteneded Performance for the 10,000 mile interval that you had planned.
The cars I had mentioned above all are mechanically sound, and do not burn or leak a drop of oil to this day. Just make sure that you keep dirt out of your engine by filtering it correctly with a quality paper filter, and 10k changed with Mobil 1 will not be a problem.
Thanks Rob for the info. The fact is my Cavilier has 100k now on the 2.4L DOHC engine and I have not noticed any oil consumption with the M1EP in 6000 miles. I may try the 15k OCI on my next change after this first 10k OCI.
I also have a Ford Explorer with the 4.0L SOHC and have 3500 miles on that change of M1EP.

i change my mobil 1 5w-30 every 4500 miles. it starts to get black then. just remember the oil may last 10k miles for you but that doesn't mean the oil filter is doing it's job anymore.

What you know about Street Racing anyways? Only what Fast & Furious taught us....
SO EVERYTHING!
I still change mine every 3,000 miles. (5,000 kilometers
) Mobil 1 5W30 and oversize AC Delco filter (PF-59 I think?)
Can't hurt... changing the oil regularly is cheap insurance

Totally agree ^^^
Even if I wasn't spraying nitrous and change oil frequently for safety sake, I would still follow the 3K guideline (I'm also running Mobil 1.) Extended formula or not, it's DEFINITELY cheap insurance.
To all Mobil EL users. READ THE BACK OF THE BOTTLE. The oil only works if your drive everyday at optuminum conditions. In really cool red letters it says that the manufacures oil change recs are to be followed.

The Pre- "Extended Performance" formula of mobil 1 was API approved, and thus had to meet oil guidelines. This gave the syntheic oils life a ceiling, because to be API certified, the oil needed to have a lower ammount of the chemical ZDDP, which greatly extended the life of engine oil. That formulation however has been showed by many UOA's through blackstone Labs and other oil analysis labs to protect your engine for about 7k-11k intervals depending on what sort of engine you have.
The new Mobil 1 Extended Performance does not have the API crest however, because it is a motor oil that greatly exceeds the API standard in ZDDP and other agents that greatly extend the life of a motor oil. This is a "use at your own risk" motor oil, because without an API seal, if there was ever any engine damage due to oil (which is unheard of, even with the cheapest of oils) then the damage would not be covered by a dealership for the car.
The reason why a Super motor oil like Mobil 1 EP does not meet API standards is because it can effect the catalytic converter on engines that burn oil where they should not! This is mainly result of very high ZDDP levels.
Amsoil motor oils have been non-API motor oils since the 70's, and they reccommend 35,000 mile oil changes.
I would never do that, and the BITOG site I posted above has proven this is near impossible, but both Mobil 1 and Amsoil can easily go 10k, and even 15k before having the same engine protection a convention motor oil would have at 5k.
Lastly, The engine oil filter has a very small effect of engine oil life when compared to the quality of the air filtration.
I actually think BITOG has results for tests where an oil filter was changed every 5k on a 15k run of Mobil 1 and then a run with just one filter, and the results were pretty close.
As you guys can probablly tell I used to be a BITOG member. An oil nerd.
I will agree that changing your oil IS in fact cheap insurance, but you can indeed change your mobil 1 too early.
I do 6000km then a clean change. Very stingy on oil. ALways Mobil1.

I just changed mine yesterday. I used it for 3,500 miles and always use Mobile 1 Synthetic.
My driving habits are: short trips, under 10,000 miles a year, and spirited driving. Given those factors, I don't mind changing my oil at 3,000-4,000 miles (even using Synthetic), which only translates to about 3 oil changes a year. It's certainly not cost prohibitive, especially to do it yourself for $20 for a 4 quart bottle of Synthetic and a $5 filter. At the very least, it's preventative maintenance.
Circumstances are different for everyone, so just use common sense when taking care of your car.

i am using amsoil and i plan on changing the oil every 10,000 miles and chande the filter every 3,000 miles or so
i have 16,000 miles on the car. and it has had this oil since around 11,000 with a filter change around 14,000 and toped it off. it has had synthetic since 1,800 miles
see ya!
I live in Dust Ball USA (Tucson). I'm not takeing the chance so it's 3k for me.
i run the Mobil-1 full synthetic & a/c delco filter and i still change mine every 3,000 miles, But then again I only put on about 6,000 miles or less a year.
My car was made with wrenches, Not chopsticks.
wow alot of you use mobil 1 synthetic....i use penzoil platnum 5w-30 syn. and change every 3,000
Moms & Dads talk to your kids,before its too late,tell them to say no to aluminum wings.
M1 synthetic (not extended performace) and I also do mine every 3k. I know I could go longer but I just feel better doing it every 3k. I've seen various studies that show M1 can go for more than twice as long. That's to say the oil itself will hold up, doesn't mean it won't get dirty just as fast.
I will never understand the use of, and cost of that type of oil in a basic motor.
You can save soo much money just using the cheapest oil you can get, and changing it on a routine basis.
Unless you have a race engine, why do it?
It makes zero ecomonic sense for the majority of the crowd.
Ask yourself this question.
Did my car come with that stuff?
NO, why?
Because it does not need it.

because if you only want to change the oil once every year. or want better MPG, have more power less start up wear. as a matter of fact. hard starting is how amsoil started the whole automobile synthetics. he was in a cold climate and was a pilot flying piston powered planes and used their synthetic oil in his car and noticed that his car started much easier because the oil was not as thick when cold as regular oil. and that started the whole thing. real synthetics tent to keep your engine clean and the engines wear less. I use synthetic trans fluid also and power steering fluid also. all to keep my car running as well as it can saving me gas!!! he// synthetic everything down to the chassis lube. try it you will have a better running car saving you money in the long run. and cheap oil builds up sludge because it breaks down with heat.
see ya!
03eco: Using synthetic can prolong engine life when used properly. It's got more additives and less detergents than in organic oil, which can eventually lead to seal breakdown or failure. The organic oil breaks down faster as well, so when it breaks down it's not protecting your engine as effectively as possible.
Do our cars come with that stuff... No. Dealers don't use synthetic unless manufacturers require it. It falls down to a cost issue for the dealerships. But, they will recommend synthetic if you ask them about it.
My Kawasaki 1600 cruiser came from the factory with Synthetic oil in it and they recommend nothing but. Granted it's a high performance engine, but still, the reasons for using it are the same.

Changing dino oil every 3000 miles costs me the same as changing my synthetic every 9000 miles.
It doesnt matter what type of engine you have, no engine is to cheap for the perfect oil.
It saves time and money.
Lets do the math:
Take an average driver that does 15k a year:
$22 for a 5qt jug of mobil1 extended performance, and $5 for the filter, thats $27, for 1 year
Vs
Dino oil at 3k change intervals, lets say it cost you $7 for a 5qt jug and $5 for your filter.
The average driver that does 15k a year would need 5 oil changes at $12 a change, this is $60.00
$60 a year, and taking the time to do 5 changes, or $27 dollars a year, and changing the oil once every year, say every spring.
I have 3 cars in the mid-200k's and they have all had 10,000 mile oil changes since the start with mobil 1, and they all run, are sludge free, and have no mechanical problems, burns or leaks.
1979 Grand Prix (Sold, being restored by an enthusiast 178,000+ still driving)
other maintenence(fuel filters, and tuneups)
Synthetic every 5-7K
Castrol Syntec
1989 Bonneville (Still family owned 187,000+ and ticking)
maintenence (2 alternators, 2 water pumps)
Synthetic every 5-7K
Castrol Syntec
2003 Pontiac Sunfire (49,000 and counting)
maintenence (fixed fog lights twice, upgraded suspension)
Synthetic every 5-7k
Castrol Syntec (found out the crap was actually a blend)
then Mobil 1
The Mobile high mileage is not a synthetic oil BTW. It doesn't say synthetic anywhere on the container, it's a high mileage dino oil.
And on the use dino oil over Mobil 1. Synthetic oil has been proven to reduce wear on the internal components of an engine.
None of those cars ever had any engine problems, and are all well over what many would consider a domestic motors engine life.
and YES, there ALL pontiacs, and if the Solstice turns out to be the miata eater it should be in autocross, I'll be getting one of those too.

Extended Performance is a synthetic oil. "SuperSyn" is there Synthetic Oil name, its a full POA synthetic oil, one of the few: Mobil 1, Mobil 1 EP, and Amsoil. All you have to look for on the bottle is SuperSyn.
IIRC, filters last 3000 miles, while the oil can last far longer, try changing the oil filter every 3k miles (ie PF 47 or 46 depending on if its an LN2 or LD9)
I use the Mobil 1 full synthetic & change it about every 4,000-5,000 miles w/ a filter change in the middle at around 2,000 or so. That was w/ the AC Delco filters. I am now using Napa Gold filter's in all my cars & have been changing the oil around 4,500-5,000 miles!
