I’ve noticed a big difference in engine noise after using Amsoil 15W-40 Diesel motor oil. The engine runs a lot quieter on Amsoil than the Shell Rotella T6 that I was using.

Never disappoints. Stellar oil analysis results, even on extended miles. The engine barely wears anymore.

Great products

Can’t say enough about this stuff! I’ve been using this diesel oil for years and I love it. I put Amsoil in all of my vehicles even the dirt bikes and the side-by-side! Everything! It is second none and if you want longevity out of your vehicles it’s a no-brainer

I have been an avid supporter of AMZOIL for over 20 years. The only lubricant company I will use in my spouses’ Lexus ,and my 6th Ram truck. I use my truck daily towing an average 8k lbs business trailer 99% of its 109,000 mile life so far. ALL fluid changes ie; gear ,transfer case , transmission, engine, cooling is AMZOIL. THIS VEHICLE LIVES SEVERE DUTY! I am also a preferred customer, the extra nominal cost is well spent money. As far as delivery time, I make my order on Monday and usually receive Wednesday. Customer support, top notch! I refuse to use any other synthetic product company, Mobile1 does not hold a flame near AMZOIL!

It's something about using AMSOil that makes you excited to change your oil. Been using it in all my vehicles, dirt bikes, mowers, and tractor for years. Not going to say anything about it keeping my stuff running well in case something breaks tomorrow, but...

I trust Amsoil products in all my vehicles and they have never let me down. They cost more but they’re worth it. Also their customer service is outstanding!

I have been using Amsoil Oil products in all of my vehicles since 2008. 07 3500 6.6 Durmax, 97 surburban, 06 HD, 02 Tahoe sold 400k Plus miles, 24yr old Dixie Chopper twin Kohler engine 72 " still running, power small engines eqpt, Purchased a new 20 surbura legacy , skip the free Dealership oil service, Back Hoe the pound out grease is amazing. I use 89 octane in all gasoline engines , my maint. has been kept to a min. Thanks AMSOIL ! great products !

Great product especially in colder weather on engine start-ups. Engine doesn't clatter as it has before when using a higher viscosity oil. If all the Amsoil testing is validated then I know I am getting the best possible protection for my trucks. My '04.5 Cummins HO truck that I bought new has never had an issue with the engine. Still going strong. Very important to not only have the best oil for your engine but for the life of that turbo as well.

Great products and 💯🇺🇸 made. Customer for life!!! I love the guaranteed protection on the parts the oils come in contact with. Switched from R**** P***** after using them for 13 years and can tell my motor is running smoother.

I used this for my newly rebuilt 1990 Jeep YJ 4.7 stroker. 4.2 Jeep motors were known for noisey lifters after the engine is up to temp. This oil has dramatically quieted my motor down. My oil pressure is 7psi higher at idle and 12 psi higher under load. This is compared to Rotella T6 15w-40. My cold start lifter tap is HALF the time (in seconds) that Rotella was. Let's say Rotella was 2-3 seconds of noise. Amsoil Diesel 5w-40 is 1.5 seconds of tap in the morning on a cold start. I was a faithful Rotella user for years. Well now I am loyal to Amsoil.

wanted up upgrade to the 5W-40 for the winter starting performance over my previous 15W-40. The oil pressure does come up a little faster.

made the switch to Amsoil based on previous experience using 10W-30 in a 86 Bronco II and a 88 straight 6 F250. Also, reviews from a couple of diesel forums gave good reviews. i have made 3 oil changes to my 6.7L and the oil coming out doesn't seem to be as gritty as the syn. penz. i was using.

I decided to use this oil in my 2015 F-350. It seems to be doing much better than the old oil I was using. I will be using this oil from now on.

Good oil for a reasonable price super quick shipping. Great staff to deal with.

It gives peace of mind knowing that the engine is protected.

Exceeds standard. Great product

Have been using Amsoil for over 38 years

It’s comforting knowing your using the best product available.

I run Amsoil in everything truck I own.
