Extend Oils Changes With AMSOIL
Calculate your savings using AMSOIL vs your present motor oil. .
AMSOIL has recommended 25,000 mile/one year drain intervals since 1972.
"I was always told to change my oil every 3,000 miles if I wanted to keep my car running well. How is it possible to drive 25,000 miles without an oil change using AMSOIL, and will extending my oil change interval void my warranty?"
AMSOIL Synthetic Motor Oil, in gas aspirated engines, is RECOMMENDED to run for 25,000 miles or one year (5W-30, 10W-30, 10W-40) in a mechanically sound engine, providing of course, the oil is kept free of contaminants by changing the oil filter according to the manufacturer's recommendation or, when using an AMSOIL Oil Filter, changing the filter at six months or 12,500 miles which ever comes first. Amsoil coined the phrase "extended drain interval" and it's been validated by almost 30 years of industry testing and by hundreds of thousands of motorists and millions of over-the-road miles. Based on their results, 25,000 miles is a conservative estimate. Other Amsoil engine oils, 15W40 as an example, carry a recommended change of two to 3 times the normal manufacturer's recommended change interval.
Why are AMSOIL synthetic motor oils good for extended drain intervals?
Does extending oil change intervals void new car warranties?
No. Automakers warrant cars against failures or malfunctions due to manufacturing defects for a period defined by time or mileage. No maintenance practice such as extending drain intervals, can render the warranty null and void.
We appreciate your attention to this matter and anticipate no further misunderstanding regarding synthetic motor oil.
Just a few testimonials for extended drains
Francis Ormiston's 500,000 mile pickup
Francis's 1969 Cheverolet 1/2 ton pickup with a 396 V8 engine has seen some miles! This is a pickup that Francis used on his large farm in Kansas and during the summer of 1986 one of his farm hands "rolled" the truck. As a result, not wanting to do anything with it (it was totaled) he pulled it behind the barn and let it sit. In August of 1989 he decided to replace a diesel engine with a gas engine in another pick up and decided to use the "69". At that point the 69 had 535,372 miles on it, 447,372 using AMSOIL 10W40. The oil was changed only one time per year (in early spring). He decided that with 535,372 miles on it (never touched by a wrench) that it might be a good idea to rebuild it before installing it in the other truck.

THE PROOF: Duluth Police Department Demonstration; 4 Police squad cars, 6 months duration, 34,600 miles on the average, equipped with AMSOIL 10W-40 Engine Oil, AMSOIL Full-Depth Oil Filters, AMSOIL BY-Pass Oil Filter, AMSOIL Lifetime Air Filter.Material and maintenance cost for the 4 units with conventional lubricants and filters was $1,052.11. With AMSOIL Lubricants and Filters, the total was only $638.20 - nearly 40% saved per mile!AMSOIL saves in labor and material costs because it can be used many thousands of miles longer than conventional lubes.

Semis Have Gone 200,000 Miles Without an Oil Change Danny Howell, Director of Maintenance for Dallas Carriers Corp. in Rockwell, Texas, conducted a demonstration in which semis were installed bumper-to-bumper with AMSOIL LUBRICANTS. AMSOIL 15W-40 Diesel Engine Oil was used in the engines, and AMSOIL Synthetic 85W-140 Gear Lube was installed in the transmissions, rear ends and the power train. Periodic oil analysis determined AMSOIL 15W-40 was serviceable after 200,000 miles and the engines had minimal wear. AMSOIL 85W-140 was also still serviceable in the transmissions after 200,000 miles. Howell reported that both the rear ends and transmissions operated like new with AMSOIL 85W-140.From: Testimonials Volume VIII
Gil Dodgen, Garden Grove, California "I just thought I'd drop you a note to tell you how great AMSOIL has worked for me. I put the 10W-40 in my '79 Honda Civic at 5,000 miles. The car was going 5,000 miles on a quart of oil at that time. I've changed the oil at 25,000 and the filter at 12,500 as recommended (I even got lazy once and changed the oil at almost 30,000 miles.) Now, with 135,000 miles on the car, the little Honda still goes.... and I still get 5,000 miles on a quart of oil! It would appear that the engine has not worn significantly. At this rate I'll get a half million miles out of the car. I just put your oil in my new Toyota at 6,000 miles and the mileage jumped 3 miles per gallon -- a 10% increase.I can't understand why everyone doesn't use this fantastic product."
Dennis Wright, Dennis Wright Farms, Albany, Ga. Dennis was amazed that on his John Deer Irrigation engine (normal oil change every 100 hours) he was able to extend his oil change beyond 600 hours with AMSOIL AME15W-40 and AMSOIL By-Pass Filters. Oil anaylsis taken at 600 hours showed NO BREAK-DOWN of the oil, very low wear metals and 8.6 acidity. His comment was that he was amazed that even in the hottest of our summer (103 degrees) that engine did not overheat!
