Customer Ratings & Reviews

I have always used the dealer to change the oil in my truck (two or three oil changes). I decided to use this oil and my engine started the well known typewriter tick. This bothered me even though GM has a TSB about the ticking noise. I couldn't help but wonder why all of the sudden the ticking started. So I changed the oil with another brand (hint - they make GM oil) and the typewriter tick stopped immediately. I have reached out to Amsoil to see if they wanted me to try a different weight/model oil, but they quickly told me they didn't "give out free oil". In my mind, this was a failure in their oil or their recommended oil solution for my truck. Given Amsoil is a premium brand, I expected much better customer service (at least a refund - which they didn't offer). I can't recommend this oil due to the ticking caused by it, and will not use their products again due to their customer service treatment of my concern.

Great oil for the price, longevity is also great.

My son has used this oily for years in his Duramax and has had no issues whatsoever with it.

High quality diesel oil.

Amsoil is the only oil I will ever run in any vehicle I care about, I am running this oil in my 6.0 powerstroke, great cold starts in the winter, I’ve had buddies with stiction issues switch to this and cure that after a few hundred miles, not saying it will fix your issues but it’s worth a shot, but I can assure you it will give your engine and injectors a longer life this is top notch oil.

There is not another product like this oil. Its the best. I order it online and it arrives to porch in 3 days. Love it. Use it in all our vehicles.

This is really good all my engines stay cleaner longer, can really tell a difference when I pull the dipstick

I've got a 2018 F250 powerstroke and started using shell rotella T6 for the first few years. After researching Amsoil I decided to give it a try and have been very pleased. Amsoil is definitely a better product, it allows for longer oil change intervals with still keeping the recommended viscosity parameters. It seems like my powerstroke runs a little smoother and quieter. I truly believe it's worth the money.

This is great oil for diesel tractors. I have used this oil in my 2 Mahindra's for ten years. The oil stays clean and ends up getting changed based on hours, but not being dirty or breaking down. My Brother in law uses the ADP in his new 2500HD, and he is having a very good result with improved mileage.

First time using this product. Heard good reviews so I thought I would try it. After ordering, items were quick to get here. Seems to be doing good so far. Ordered it for my car and my deisel truck.

Heavy-duty, long lasting preferences

I ordered the 5w 40 oil kit for my diesel truck and I love how they send the exact amount of oil you vehicle takes and the WIX oil filter. All hassle free in one kit, shipping was very fast plus it came with an amsoil sticker, you don't see that often these days anymore. Thanks!

I love my truck, and I will only put the best product in it. Filters & oil, plus anything else I need will always come from high end companies like Amsoil

Excellent product

Use this all the time. Won't be without it.

Great oil for the 7.3 powerstroke engine. The engine starts easier and runs quieter with amsoil. Great lubrication for the injectors to keep the chatter down so I know they are being lubricated well to make them last as long as possible. No stiction issue using this oil so it’s cost effective not having to add a stiction additive with it. I don’t think you could find a better product to protect your engine for the long run. I run amsoil in everything. Car, truck, motorcycle, lawn mower, chain saw if it needs oil amsoil is the only oil i use.

Use AMSOIL in my Ram 3500. Really like this synthetic oil.

One always needs an extra tomato Things off

Run this oil in my 23 6.7 power stroke. Engine has 245k and oil analysis comes back with zero issues. Analysis says I can run longer but I usually change it around 7500 miles.

We have a Ford F-250 & a Ford F-350 and if we were to take our trucks in for an oil change it's over $300 per vehicle. So we have been changing our own oil for the last three years now and with Amsoil we save a lot of money just ordering our oil and filters through Amsoil's website. We are very happy with their products.
