It is expensive, but worth every penny. Instead of replacing every 3000 miles, it is once a year!

Interval of change time is great. Better gas mileage in my pickup. Works great great product.

It seems to work. I have not analyzed any gasser oils yet but Amsoil was great in my diesels so I figure they can handle gasoline which is so much cleaner.

Great oil.

I use amsoil inn both my vehicles. Both tractors and mowers.

Used in a new Dodge Caravan and works great

I use this product in my wife's new 2017 Hyundai. Since the break-in period is over, I now use the 5W-20 Signature AMSOIL in the vehicle. The gas mileage actually increased slightly, and the engine purrs now, which is a change from the break-in oil. I will continue to use this oil, without doubt.

Maintain all my cars with amsoil

When I first bought my vehicle used, the oil changes looked super sludgy, and the gas mileage was pretty poor. After 1 oil change with amsoil full synthetic with the ea filter, it is clean clean clean and I have 1mpg better fuel mileage after a little over 5000 miles. With any other oil, it would be black and gritty looking. I also like the extended drain intervals provided with this oils capability, so I only have to change my oil once per year.

For some reason, my gas mileage went down after putting this oil in my tundra. I reset the computer at every oil change. I was using Pennzoil 5w-20 and got 15.8 mpg over 5000 mile span. I am nearing 5000 mile mark on this Amsoil product and my mpg is at 15.0

This product is the best deal in the long term due to the extended oil change and life of the oil. I use it in my Ford products

Great product. Prolongs engine life.

I have 170,000+ miles, after the 36,000 mile factory warranty ran out it has been Amsiol ever since. I use the 25,000 mile signature series with never a problem. I have to change the filter half way thru because I can only find a 15,000 mile filter, I have to add between 1/2 and 3/4 quart at this time. I always change oil around 24,000 miles unless I have been pulling my 7,000lbs for over 1,000 total between changes then for piece of mind I change at 20,000 miles. I drive a 2008 Toyota FJ Cruiser and take it off-road

I've used AMSoil in all my vehicles including my Harley's since I purchased them, used or new and I will never go back to off the shelf products again. The cost difference is insignificant so it only makes sense to use the best.

Had some other people talk about benefits of Amsoil. Started using it in my '98 Ford Ranger with 108,000 miles on it. Sent in samples and at 185,000 miles truck was cleaner engine wise then it was at the start. At about 265,000 miles sucked a valve so had son put new heads on it. When tore into engine was no sludge or carbon on top of block and the timing chain looked like brand new. Son traded the truck in on newer one at 365,000 miles and still was running good. I use Amsoil in all my vehicles and yard equipment.

Several years ago I was looking for a high quality full synthetic oil for my motorcycles and after I did a lot of research I decided to go with Amsoil. Since then I have become a preferred customer and I use Amsoil products in all my vehicles. I trust Amsoil products and I would recommend all their products.

I added Amsoil 5w30 Signature to my 08 350Z HR. I noticed an increase in power immediately. I'm running against cars with much more power, and outperforming them, thanks to what feels like quicker acceleration through the rpm range. I recommend this product for all engines, as no other oil comes close.

Use in my Tundra, lasts longer, cost effective and better quality than whatever the dealership puts in.

Last time we had to order amsoil we received free shipping. That just added to the great deal we already get from them. We've been using amsoil products in or vehicles for 2 years now and nothing else compares.

I put Amsoil in ALL of my toys.
