Syn.Lubes change intervals

[jeanne penrod]

Friends, The biggest problem faced by any power plant is short
run times.The engine does not reach operating temps.long enough to burn off
ANY condensed matter formed.Our coachs are not fired up to run to the 7-11
to by Twinkies,you get in em and go along ways!! Log the uses of your
personal family hauler,check the time it takes from your house to the first
stop,lok at the temp.gauge and note where the needle is ,time your stay,get
back in and go to your next stop,note time & temp. go to your next
stop,your get the pattern.Each start and stop is a heat up cool down
slightly,condensation building cycle,without enough time to burn off
anything. Under these conditions,re:every day driving,exhaust
systems,suspension systems,and yes your oiling system,takes a h...of alot
of abuse. My coach ,bought in Dec.was driven home from Alex Sirums about 40
miles,back to alex's for Ramco Mirriors and Maint.another 40 miles times
2.then to Warner Robbins,Ga.for christmas 480 miles going and 480 miles
coming.Sunshine Statesmen rally Dover,fl.100 going 100 coming.When and
Where is my beauty going to start building sludge in the crank?
Can you extend the miles between oil changes ? Sure you can! Should
you,personal choice,pure and simple. Jim penrod

You hit it on the head Jim, its the short runs that hurt your engine and
drive line components, because the water vapor never gets burned out of the
crankcase.

Everyone is missing one essential point however. OIL DOES NOT WEAR OUT!
Pure and simple fact.

If any had looked at the Cummins engine URL that I posted they would have
seen that.

Can you extend the oil change intervals for oils? Yes. Can you extend the
service life of synthetics? Yes. Amzoil suggests 25K miles between oil
changes with just a filter change between. In my opinion synthetic oil
changed at this interval is far superior to conventional oils at 3000 miles.
Mobil 1 ran a BMW 525I for 1,000,000 miles and the engine was still within
new BMW engine specs. Read about it on their site.

Another myth debunked.

It may not "wear out" but, unless you have the equipment to separate the
oil from the contaminants, it's a moot point. As Fred pointed out in
his excellent post, you need to get rid of the accumulated acids and
combustion by-products and the easiest and most economical way for the
majority of us to accomplish this is an oil change.

IMO, "good" reasons to change to synthetic lubricants are:

1 - Reduced wear and tear(better lubricant).
2 - More resistant to thermal breakdown under heavy loads.

"Bad" reasons to change to synthetic lubricants are:

1 - Better gas mileage(I doubt you'll notice the difference).
2 - Extended service intervals(Oil, even expensive oil, is cheaper than
engines).
3 - Reduced oil consumption(depends on the condition of your engine -
might actually be worse)

Did you notice that Mobil1 very quietly dropped the extended service
interval pitch from their advertising? Check out the data sheet at:

http://www.mobil.com/oneracing/about/products/engineoil/10w_30/index.html

The million mile BMW had its oil changed at the "manufacturer's
recommended oil and filter change intervals". The data sheet also
states "Owners of all cars, should follow the car makers'
recommendations for oil drain and filter change intervals."

While Amsoil has good products, they've taken some flak for their
marketing and hype. I think I'll take Mobil1's advice.

Not in my opinion,
