Great oil

I have been in the automotive industry for 45 years and have seen all kinds of oil and lubricants. Many claim amazing things. My personal experience with Amsoil has been long term. First my race bike. Nothing compared to the performance of Amsoil. Runs cooler, lasts longer, overall good results. My truck now has 343000 miles. Still does not use any oil. My Harley picked up 3 miles/gallon and runs cooler.

Just recently changed my C6 Corvette to Amsoil. Looking for cooler operating temps and the reduction of lifter noise on cold starts. Took a 200 mile trip ran about the same temps as my previous synthetic oil. Engine seems a little quieter with cold starts. The cruising season is just getting started her in Ohio. The true test will be when I track the car at some of our clubs autocross races and high speed events. Two other friends have witnessed improvements with this product and switched based on their recommendations. They both race frequently and push their Vettes to the limit without any issues.

Bought a Ram pick-up with the 6.4 hemi. Needed some oil and found this product. Been using synthetic oil in all of my vehicles. First time using amsoil, I believe it will work for all my needs. Very pleased with the product and will continue to purchase. Once I use my supply up for the wife's vehicle, I will buy amsoil for her car also.

seems to be working good. I put a 100,000 miles a year on. does not keep engine as clean as redline. lots of varnish from amsoil at the 100,000 mile mark. redline at a 100,000 looks just like knew inside the engine.

I use this in a 2003 Chevy pickup I like being able to change once a year. My brother uses the same oil in a 2004 GMC at 130,000 the engine was taking a quart of oil every 2,000 miles. The first fill with Amsoil Signature 5/30 at around 6,000 miles the engine dropped oil consumption to almost nothing. The engine would use a quart after that about every 10,000 miles. He changed oil every 12,000 or so and the engine finally gave up with 285,000 miles

I started using it in 2009 on my 1999 F150 with 75,000 miles. I put about 10,000 to 12,000 mile on the oil per year. I now have over 162,000. When I look thru the oil fill opening the cam shaft looks new and I see no signs of sludge or wear.

I started using this oil many years ago. When first bought it I used your oil filter and oil I put in my Ford 150 pickup truck 2002. I left in my truck for 6 weeks and drained the OIl and put in new filter and oil this cleaned the inside of my motor now the oil stays very clean. I now have over 363,000 miles on my truck still running strong

Best synthetic on the market. It's the only thing I use in my truck.

I always say that if Amsoil don't know how to make Synthetic Oil NO ONE does.. Because they have been the first since 1972..

Use for my car

Super impressed with all The Amsoil products. Extebdes oil change intervals makes it a no-brainer. vehicle Vehicle runs so much smoother, better gas mileage, it's a win-win

Great products

Amsoil protect my crankshaft when my oil pump failed and I get better gas milage, epa rating for my car is 35 mpg and I repeatedly hit 40 mpg.

2010 Toyota sequioa w/ 200k on the clock. Doubled oil change interval to 10k, doesn't use a drop between changes. Frequently idle and tow in hot Mississippi weather. Noticeably quieter valve operation over other top shelf synthetics. I just did a 200k service and noticed there is zero sludge in the engine. It was as sparkly as a transmission. I expect 300-400k out of this engine but it is a Toyota not a Ford!

I use Amsoil in everything machine I own. That Amounts to one diesel pickup to three gas pic up and two mustangs one being a 2011 Shelby GT500

300000 miles with once a year oil change. Amsol is the best

I say this product would out perform Mobil 1. Great to extended your drain intervals

The best oil I've ever used.! Hands down!

2013 Kia Rio o my has a 3.5 qt capacity. Best oil I've seen for this scenario
