Koz is correct in that the OLM system was developed by an award winning GM team lead by one of the foremost lubrication engineers in the world...and that is gospel.The 3.6L engine does not have an oil cooler. In lieu of the cooler, GM has issued a spec for high temperature performance; GM4718M. GM has issued a list of the oils that THEY have tested and approved. Other manufacturers can claim they meet the spec but can't prove it. Look for the GM4718M seal on the label. The factory service manual says you can run the OLM to 0% or for one year. You then have two fuel fillups to get the oil and filter changed. The GM OLM system was developed by an award winning GM team led by one of the foremost lubrication engineers in the world. You can take the readings for gospel. Anybody pooh poohing the OLM system is displaying gross ignorance.
No, not at all......that sounds about "dead on" accurate if you remember that synthetic motor oils are designed to provide about 5000 to 15000 miles of use on average based upon your vehicle driving habits.Iam guessing my change wil be due at about 15K kilometres. Approx 9300 Miles. Too much ?
My thoughts are you're in the wrong forum :tisk:My Cub Cadet 7 horsepower lawn mower did not come with an Oil Life Monitoring System.
Can anyone tell me how often I should be changing the motor oil?
Also, does it make a difference on how often I should be changing the oil if I am bagging the grass clippings versus mulching?
It just occurred to me that mulching may increase the "deck temperature" of the lawnmower and cause the oil to break down sooner. Is this possible?
I do notice when I am bagging the grass clipping; the lawn mower does seem to run a bit cooler as I don't get those awful 3'rd degree burns on my hands when I touch the muffler.
Massaging and refining the OLM alogarithm is an ongoing process. The original testing determined which measurable engine operating conditions best predicted service life of the oil. The beauty of the OLM system was that all that was required to validate it's use with other engines in the GM lineup was to compare oil analysis data collected during specific testing with the original data and verify that the oil condition was affected in similar ways by similar operating conditions. It's no mystery why Dr. Schwartz has the respect of her peers and why GM has extended its engine warranties to 100,000 miles.Koz is correct in that the OLM system was developed by an award winning GM team lead by one of the foremost lubrication engineers in the world...and that is gospel.
It is however my understanding that the OLM algorithims were written over a period of 16 months of collecting data on internal oil temperature, RPM load, thermal breakdown, coolant temperature etc on an LS1 "stock" engine in developing the Oil Life Monitoring System.
That being said Koz, is each OLM systems algorithims specific to each GM engine platform or is the OLM system that was developed for the LS1 based Corvette simply carried over to various other GM engine platforms such as the 3.6 VVT platform?
And what is to be said of the OLM system with regard to engines that have been modified from stock?
I would agree that it is fool-hardy to throw away perfectly good synthetic motor oil at 3000 miles.
I'm not pooh poohing the OLM sytem.....I simply change my vehicle oil typically between 5000 and 7500 due to modifications and would prefer to err on the side of being conservative.
Nevertheless; even if the OLM system stopped working tomorrrow; you still have your odometer and good common sense as to when is a reasonable time to change the motor oil I would think.
Not sure I know what you mean exactly, but as far as i know ours are identical except for some differences in standard equipment/option packages and we get a speedo that goes up to 260 (since we use km/h).GT: off topic thread; are the Canadian version CTS's sold with the red&white rear back up lights as are the Euro versions?
