Mobil 1 7500 mile ??
 

Has anyone tried the extended life version of mobil 1 ? What are your thoughts :lurk: ?

Be careful Bob.
The 7500 is NOT Mobil 1, but a synthetic blend.
Only the original Mobil 1 and the Mobil 1 Extended Performance (15000 mi) are "full" synthetics.
Simply put, if the "1" isn't on the label, it's a blend or Dino.

I have used the 15K extended....it actually lasted longer than the regular Mobil 1....IMO not enough to justify the $4 a gallon...

and before I get all the naysyaer :bs I change the oil by the DIC always at 20%....drive the car the same way etc. based on mileage I did a bit better..maybe 1000 miles.....of course YMMV and you can KMA if you don't like it :jester

The oil life monitor does Not know what kind of oil you have in the motor....
Mobil extended life synthetic does not meet GM standard 4718M. Not all synthetics meet this guidline.Using a non approved oil will cause damage to the engine, and void any warranty.
It must say GM 4718M on every bottle.

This is right from the Mobil website:
Mobil 1 Extended Performance meet all the requirements for GF-4. Additionally, they exceed the requirements of API SL/CF and various ACEA (European) specifications. (Updated March 2006) .

It does not meet GM's spec, therfore will void your warranty and will cause engine damage over time.

it further states on Mobil's website that they will not be responsible for damages cause to engines where this product does not meet the manufacturers specs.

lol this is coming from the same company that gave us the column lock.

If you are not happy with you car, sell it. try to find a perfect car.,,,
People like you make me want to puke!
Im offering information which could save them thousands of dollars and keep their warranty intact...and you post this crap...

$4/gal = pretty cheap.

:iagree: I run my oil life down to 0% - 2%, usually about 12000+ miles.

Mobil Extended Life synthetic ??? pretty cheap???
Ls/x engine pretty expensive

30 -40% here then it's changed.

I don't drive that many miles a year so I just change yearly with Mobile1.

Oil
 

I use Mobile 1, change my oil every 3000-3500 miles. The only time I care what the DIC sez is if I haven't hit the 3000-3500 mile mark and its a bad %. I Personally would never go past 25% as I consider the potential for disaster increasing with every reduction in %. I am in very heavy traffic and no matter what I change my oil. $4.00 a gallon! I wouldn't buy it can't be very good oil, synthetic or otherwise, unless its Dino. The caviot being that Mobile 1 or its equivalent synthetic is necessary for the proper performance of your Corvette.

When I buy a used Corvette; if they don't have the records and haven't used the right oil for the car I won't buy it, no matter how good the price.

That's how important the right oil is for worry free performance and extended engine life. If the oil isn't right odds are the rest of the maintance and care for the Vette was slip shod and half-assed as well.

FYI.. most manufacturers bench test their engines for 100,000 miles , it is a bench mark.....
Ls/X engines were bench tested to 200,000 miles.....
it is a credit to sound engineering and a great product like Mobil1 synthetic...
There is no other V8 4 stroke aluminum engine in the world that produces 350 hp and regularly see 200,000 mile life cycles.

Change your oil every 3000 miles REGARDLESS of what the DIC says. Especially if the car is parked in an outdoor environment. The DIC cannot measure environmental conditions, condensation, salt air , air borne pollutants , suspended solids in suspension that find their way into the crankcase and acid contents in the crankcase. It just gives you best guess on a variety of engine running paramaters not always indicative of the real world . Be safe ...every 3 k max. I don't like guesswork.

Manufacturers specs are designed to ensure that the car can meet the designed service life. As E-T states the LS/x are designed for 200,000 miles. Why would anyone want to put in an oil that does not meet the spec?

thousands of hours of testing over three years with oil test data were loaded in to a computer ... every scenario imaginable was used and actual oil test done.before the algorithms where written. GM even built a safety factor into the algorithm.. the oil life monitor is so good that in 2001 they raised the base line from 10,000 miles to 15,000 miles... Use the oil life Monitor down to 0 and you will save a few bucks and save the environment, save the whales, a stop the senseless slaughter of the seals. :smash:

Well...with this kind of 1970's thinking, the people who sell oil will LOVE you. It's not necessary to change your Mobil 1 oil every 3000 miles. It's a waste of time, money and ofcourse oil. :eek: But, I guess if it makes you happy, do it... :lol:

wait, your supposed to change your oil??? i have 82,000 and never change ....


only kidding i do it every 3000 and i really do have 82,000 and trouble free from day 1 and btw its a 02 vette

Okay, I guess i opened a bag of snakes. I have a cousin who owns a trucking company and has rigs that do 300.000 to 500,000 a year and they use Mobil1 exclusivly. Their SOAP samples tell them that they could get another 20,000 per oil change :lurk:
