The only oil I can find that is full synthetic AND meets KIA's turbo- direct injection standards PLUS has a warranty to boot! All I use.

Used Amsoil on my old truck that still run strong when I sold it with over 240000 miles on it so I'm started using it on my new F350 starting at 3000 miles on it.

I use it in one of my high horsepower LS3 engines that I have built. It nears 600 na horsepower at the crank and 500 rwhp, and it is a daily driver. Only thing I trust is the 5W30 Signature Series.

I have been using Amsoil for several years. I can tell that my car engine runs quite and smooth. I like the longevity of the oil. I usually change the oil once every 10,000-15,000 miles. It saves you money and time

I love this oil! I have an oil catch can to catch the sludge buildup and it hasnt catched any. I've been using this oil for about i'd say 3 oil changes since I switched from Mobil 1. Never going to any other oil. Superior protection, cleaner engine, better gas mileage...best oil ever! Amsoil is the way to go!

Great

I've heard from too many mechanics and truck drivers how much longer engines last with amsoil synthetics. I don't drive much so one oil change a year with a filter change in 6 months is all I need.

I've been an AmsOil customer for probably 15 years. I've use AmsOil products in my Surburbans, Avalons, motor cycles, and small engines. Pre-pandemic I used to be a 10-14k/year driver for both vehicles. Consequently, I'm a once-per-year oil changer. Granted, the Sub takes 8.5 qts and the Avalon requires 6.5 qts. I've NEVER worried about lubrication issues with AmsOil products. I sold an Avalon after 207k miles with ZERO additions between annual oil changes. The Chevy's are maybe 1/2 quart between changes, but I pull a boat to Canada at least 1x/year so that's to be expected. Although purchase price is a bit more than other products, long term costs are less $$ due to the longer change intervals. When I bought my Yamaha FJR1300 motorcycle, the previous owner had AmsOil on the shop shelf which made me more confident in my purchase, even though it had 36k miles. It's a no-brainer.

Best oil especially for my older toyota vehicles.

I thought it was a great product

I’ve run it in my last 3 cars almost a million miles, Not one oil related problem, At 25000 oil change intervals

Used in all vehicles, oil chgd once a year or every 15k. No minor or major engine repairs, vehicles can and have exceeded 325k

Best oil I have ever used. My twin turbo engine runs smoother than with the other the brand I was using. Also, I had a great experience with their customer service. Great product and service. Customer for life.

I run this oil in my C5 corvette. This car is used for HPDE and autocross. I only have 1 season with this car but I have a decade of experience with Amsoil. I don't want to keep a spare engine on hand, so this is the stuff I want in my race car!

Great product, keeps my car running like new ,wouldn't change for anything else.

Amsoil is by far superior to any other oil I have ever used. The motorcycle oil is fabulous.My harley runs at least 20 degrees cooler in summer.I use Amsoil in every application where a superior lubricant is needed. You only get what you pay for.You get the very best with Amsoil products.My salesman Greg is the best!

I’ve used the signature series oil for years. 200,000 on my last truck never had any problems. 175,000 on my current truck and still going strong. I travel and pull a camper we’re I go with a 1/2 ton truck. I love the fact that I can go 20,000 miles without changing oil. So that’s a money savings deal you can’t beat with the cost of oil changes ever 5,000 with conventional oil.

I believe it's the best one out there for my F-150 EcoBoost

this oil is so good , i am so happy that i had found a real ' 100% synthetic

Use in 2010 Infiniti G37
