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.

only oil I use in my cars and motorcycles.........

I use this oil on all my small engines. My compressor used to trip the circuit breaker regularly until I switched to this synthetic blend. Hasn't tripped a breaker since even in the winter

I use this my children use it in my friends use this. We enjoy the fuel savings less engine friction and longer service intervals it really saves a lot of money.

used products from1997 to today

I have been using this oil for 10 years on my 2006 Corolla, change the oil once a year, now have 168000 miles and still going strong

Talking to a woman about oil is not easy, but a co worker and former mechanic was the one that got me started. I am glad he did. I have been using Amsoil oil for about 6 years and will not use anything else. I first bought it because i drive a lot of miles to work but now i work from home mostly and still use it. Amsoil has quality products!

Love the extended oil change intervals, with no harm to the vehicles

I have read on a number of websites and have heard over the years that Amsoil is the gold standard for motor oil. I finally registered for an account and am now using Amsoil Signature 0W-40 in my 2016 Ram 2500 6.4L 4x4. I switched to Amsoil at 500 miles and have just recently changed the oil again at 6000 miles. I have been getting reasonable mileage with my new truck (about 14.5 mpg average), considering I have the 6.4L and it's a 4x4. I recommend that if you plan to use Amsoil, to pay the small amount to become a Preferred Customer (currently $20 per year), because it will pay for itself in the savings per quart of oil (about $12.50 to $8.50 for the 0W-40 Signature Oil). A quick story ... I turned a friend on to Amsoil, he started using 5W-30 Signature in his 2007 Nissan Quest with 60,000 miles. As early as the drive home from my house after changing the oil, his 15 year old son with a learner's permit could feel it running smoother and quieter, and now only one month later, he is already seeing 1-2 mpg increase in fuel economy. He plans to change his oil again at about 5000 miles and will then change it annually.

I use 5w30 and 5w20 in all of my cars
