Engine Cleanliness
Deposits reduce engine performance and efficiency. AMSOIL 100% Synthetic High-Mileage Motor Oil provides enhanced detergency to breathe new life into dirty engines by removing deposit buildup to help restore peak performance.
Its exceptional cleaning power is demonstrated by its performance in the modified Sequence VH test, where AMSOIL 100% Synthetic High-Mileage Motor Oil reduced sludge by 67%,¹ demonstrating its cleaning power that helps engines last longer and perform better (see chart at right).
Further proof of performance is demonstrated with the TEOST 33C results, where AMSOIL Synthetic High-Mileage Motor Oil provided up to 62% better deposit prevention than the competition (see chart at right).
Durable Viscosity
Engines can lose compression as cylinders and piston rings wear, leading to reduced horsepower. Maintaining a consistent fluid film helps to counteract compression loss by sealing combustion chambers to maintain performance. AMSOIL 100% Synthetic High-Mileage Motor Oil is formulated to maintain viscosity, even in extreme temperatures. Its highly durable viscosity provides proper film thickness, even during extreme operation.
Oil-Consumption Control
Oil consumption is often an issue in high-mileage vehicles. AMSOIL 100% Synthetic High-Mileage Motor Oil is thermally stable across a wide range of temperatures, resisting volatility and consumption.
Leak Protection
Oil leaks are an inconvenience and if left unchecked can lead to lack of lubrication and engine failure. AMSOIL 100% Synthetic High-Mileage Motor Oil provides a boosted dose of seal conditioners to restore aging seals and help stop leaks.
Compatibility
AMSOIL 100% Synthetic High-Mileage Motor Oil is compatible with other conventional and synthetic motor oils. Mixing other oils with AMSOIL motor oils, however, will shorten the oil’s life expectancy and reduce its performance benefits. AMSOIL does not support extended drain intervals where oils have been mixed. Aftermarket oil additives are not recommended for use with AMSOIL synthetic motor oils.
Service Life
Normal Service – Up to 12,000 miles or one year, whichever comes first, in personal vehicles not operating under severe service.
Severe Service – Follow the severe-service drain interval prescribed by your vehicle manufacturer in your owner’s manual.

Love my motor
My review ,Smoother sounding motor ,knowing I'm doing the best for the motor and the love for my Truck to give it the best
Using true synthetic oil
since i have been using Amsoil 5-30 engine oil in my truck i have had no issues with low oil pressure which most garages use a cheap part synthetic motor oil which breaks down fast. So happy to have switched to amsoil great product my cost a bit more but it saves you money over the long haul if you want to keep your engine in top shape. Also my garden tractor would smoke every time you started it up but since i put amsoil small engine oil in no more smoke runs better and doesn’t use any oil. Thanks and i’m spreading the news to everyone i know, keep up the great work customer for life
Perfect
I have tried many oils for my trucks, including the Royal Highness lol but honestly Amsoil has been the best I currently have 200,000 miles on my 2020 jeep and I truly believe the oil is keeping the engine running stronger then ever. I will continue to run Ams and constantly recommend it
Great
Great stuff
Funny I have to review this
If you’re shopping Amsoil, you already know it’s the best oil out there. Easiest customer service to deal with and fastest delivery… AND I didn’t leave the couch to do any of this. Highly recommend anything Amsoil sells.
Great product
Great product protection for the engine
Always a great experience with AMSOIL!
I have been using AMSOIL products for close to 20 years now on all my vehicles (Ford P/U Trucks, Jeeps and Harleys). My vehicles just seem to run better. They run cooler, shift smoother and get better MPG. And when I do an oil change, I get almost every drop back in the used oil catcher. And to make things even better, ordering from the AMSOIL web site is super simple. Easy look-up for your particular vehicle, save your vehicle(s) in the 'Garage' for future use, package deals, and super-fast shipping. I can think of nothing negative to say about the entire experiences that I have with AMSOIL over the many years that I have been using their products and dealing with the company as a whole. THANK YOU!
A true synthetic
After intense research on all oils only amsoil finished 1st. Most synthetic motor oil only are 10 to 20% synthetic Amsoil is almost all synthetic over 80 % It stands alone as the best motor oil for your vehicle by far
As good as advertised
I’ve used this oil for two years and recently had it tested after 11,000 miles. Testing showed this oil to be in great condition, no metal and chemically still strong.
Best oil and products.
I’ve been using your oil and other products for over ten years,now two my sos do as well. Great company.
