Interstate Battery System of Detroit,
This letter is a summary of a letter received from the
President of Interstate Battery of Detroit.
I am writing to let you know how pleased I am with the
AMSOIL program that you helped set us up with. For the
past 25 years our fleet of trucks, mostly Navistar/International
4600 Series trucks, have been using regular petroleum-base
lubrication products. We thought that we were happy with
our lubrication program until we were introduced to AMSOIL.
I was very reluctant to switch from regular lubricants
to fully synthetic lubricants because the benefits of
AMSOIL seemed too good to be true. To be honest, when
I was told that the motor oil could go as long as 100,000+
miles without changing, I didn't believe it. I can tell
you now I am a true believer.
We have been using AMSOIL now for about 4 years and have
changed the entire fleet to AMSOIL synthetic lubricants.
We use the By-Pass oil filtration system on all of our
trucks with the Synthetic Heavy
Duty Diesel and Marine
15W-40 oil. We use AMSOIL grease and use the 75W-90
gear lube for the manual transmissions and differentials
and the synthetic ATF
transmission fluid for the automatics.
What do I get out of using AMSOIL? A lot! After becoming
fully synthetic on all of my trucks, I picked up an average
of 5% in fuel savings. I haven't had to change my oil
since I switched...4 years ago! I can't tell you how much
money that has saved me in time alone. I have several
trucks with over 100,000 miles on the oil and I am still
getting high marks when I send the oil in for analysis
But the best benefit is the decreased wear and tear on
my equipment such as the pistons, cylinder heads and walls,
transmission gears and differential
gears. That is the most important to me because it
means I can leverage my fleet longer, which translates
into saved dollars. It means I can put those extra dollars
to work in another area of my business. My average truck
life has gone from 7 years to more than 15 years! UNBELIEVABLE!
I have estimated the savings from better leverage alone
will save me over $20,000 per year.
Thanks for all the help as I've implemented this new
program. I am absolutely ecstatic about the results so
far and I look forward to a long and fruitful partnership
with you and AMSOIL.
