Interstate Battery System  of Detroit, Inc.

This letter is a summary of a letter received from the President of Interstate Battery of Detroit.  Please contact  us if you would like the full letter mailed, faxed or e-mailed to you.

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.

Action Tree Service Inc. of Oakland County:

Action Tree Service Inc, is one of the premier tree service companies in the state of Michigan and is often called upon to handle some very tough jobs.  Action Tree is well equipped for routine tree care, logging, climbing, large lot clearing and emergency storm response.

All light, medium and heavy duty trucks, chippers, loaders and other equipment has been converted to AMSOIL lubricants and filtration systems.  Action Tree has some of the most specialized equipment in the business, including a custom designed 80 foot in reach aerial lift bucket truck which is a 2000 model year, 4900 Series International DT466 275 H.P. diesel with an Allison New World transmission.  The company also has several large swap loader diesel trucks and Ford PowerStroke Diesel trucks. 

All of Action Tree's vehicles and equipment use only AMSOIL synthetic lubricants and filtration systems.  Every truck is equipped with AMSOIL 15W-40 Synthetic Heavy Duty Diesel Oil, Dual-Guard (for large diesels) or Dual-Remote (for Ford PowerStroke) filtration system, AMSOIL gear lube and AMSOIL synthetic automatic transmission fluid. Each of the large diesel trucks has 77 grease fittings and lubrication points which are all lubricated with AMSOIL GHD Heavy Duty Moly Fortified Synthetic Grease. Since switching to GHD, Action tree has drastically  reduced the frequency of required greasing due to the greases superior performance, while providing much improved lubrication and protection to critical components. All chippers and stump grinders use an auto lube system with AMSOIL GLA synthetic multi-purpose grease.

Owner Adam Camden states that one of the biggest improvements that they have noticed has been drastically improved cold weather starting and significantly reduced maintenance and downtime along with the security of knowing his equipment is protected with the best lubricants available anywhere.

An interesting side note is that owner Adam Camden spends a great deal of time researching, testing and going to industry trade shows seeking out the very best products and equipment.  Adam states that AMSOIL is the very best there is and continuously promotes AMSOIL products to his friends and other commercial businesses he works with and proudly displays AMSOIL decals on his equipment, shop facility doors and hangs the large AMSOIL banner at the company facility.
