I changed the oil in my 2010 F 150 to Amsoil and the gas millage has increased by by 4 miles to the gal. I am very happy with the new oil and will keep a eye on the millage to see if it stays good
Bottom Line
Yes, I would recommend this to a friend.

I have been using the Amsoil 15w40 diesel/marine oil in my Kubota tractor since it was new in 1994. Works great and keeps the engine running smooth. I'll never change to another.
i use this oil in my 8030 allis-chalmers tractor. this synthetic oil is excellent we get to 20 below zero here in the winter and i use this tractor on the snowblower and the minute the tractor makes one revolution with the starter the oil pressure light is off and it starts way easier with this oil. i am very satisfied with this product. would recommend to anybody who would want to use it. super product.
Have used this product since 1997, and still impress with it. Do oil change once a year (approx 25000 kilometers per yr) send an oil sample to Lab and return are excellent. Highly recommended
I have been using this engine oil in my Diesel Pusher Motor coach for 10 years and would not use another oil. I also have the Turbo Drive automatic oil in Allison Transmission and because this transmission is not only very good but it is an expensive one that I only want the best oil in it.
I actually replaced the recommended Castrol Transynd oil that was in it to this Amsoil one and noticed that the shifting is smoother and the temperatures are lower during use. I monitor all the engine and transmission activity thru a computer while driving so I actually am seeing what is happening at any time, so, these issues I see and not only feel.
Bottom Line
Yes, I would recommend this to a friend.

I have been running this oil for 15 years in my 2005 superduty 6.0 diesel. This truck pulls a 16,000 lb fifthwheel many miles a year. Engine does not use any oil, have not had any injector sticking, and no turbo coking. Great customer service and lighting fast shipping.
Bottom Line
Yes, I would recommend this to a friend.

I have used many oil in this truck over the last 31 years of ownership. When I put this in my truck for the first time, I immediately heard a distinct difference on fire up. It softened the harsh rattle somehow. I know this sounds silly but when you own a vehicle as long as I have this one, you notice any difference in operation. It also uses less oil. I have gone through 2 oil change cycles with this product, and each time have not had to add but 1 quart every 3000 miles, versus every 1000. That is a huge difference. I am a convert. I am even putting this in my car now.
Bottom Line
Yes, I would recommend this to a friend.

I have been using amsoil diesel/marine in my 2004 dodge cummins since it was new, never had any issues. the truck has 186000 miles on it and sometimes the oil doese't get changed for 6000 miles but always has plenty of lubricity when changed.

I have a Kubota 8200 farm tractor it has a low oil pressure shut-off in cold weather using conventional motor oil same weight it would crank and shut off using Amsoil diesel marine this stopped so oil is getting through the engine quicker so now I use in all our farm equipment
I’ve been using this Series 3000 in my 2006 F350 with the 6.0 diesel. Yes the infamous 6.0.
These are great engines built with extremely high tolerances that requires religious oil changes every 200 hours.
By using the Series 3000 I have extended my hours up to 300. I could go more as per oil sample results. But typically this is right around the one year mark anyways.
As you have probably heard, the 2006 F350 is one of the most stolen trucks in North America. I can attest to this as mine has been taken twice now.
Once from work and once right from my home address. Yes I have a security system on it now. But back to the oil. In both thefts, the engine was abused enough to crack the heads and ruin the turbo. Yep. Both times. But the bottom end of my engine has never been touched and I have not had to change my high pressure oil pump either.
I am pushing close to 400,000km on it now and it still pulls hard. I purchased it with 120,000 km on it and immediately changed over to Amsoil and put a 75hp tune in it.
Other than the thefts, I have never had an issue and I run it year round, summer and winter. Would never think of using anything else.
Bottom Line
Yes, I would recommend this to a friend.
