This product has held true to its testament. Under varying load conditions, it hangs tough. It's also nice knowing I can go 10,000 miles or 6 months without having to do an oil change. Amsoil is the best out there!

I've use this oils for the last 4 years on my car and I wouldn't think of changing. Up until recently the formula said it would get you to 10K, but now has been modified to go up to 12K. I have yet allow my car to get to 12K between changes, but I'm not doubting at all that it would last that long.

In my four personal vehicles I use Amsoil 0W-30 Signature Series and perform my own oil changes. I also perform oil changes for several of my adult children's vehicles. My brother-in-law does oil changes for his grandson who purchased one of our vehicles a year ago. He wanted to stay with the Amsoil products, but has a tight budget. My daughter's family also has budget challenges, so I have decided to use the reformulated 5W-30 XL oil for her vehicles. My brother-in-law also wanted go that route to save some money. I think it is a great alternative for exceptional protection and cleanliness (TBN 10) at a budget friendly cost.

Have been using Amsoil in my personal vehicles for the better part of a decade now. Michigan weather will eat the body off of the car but the engines purrrrrr! From small engines to ATV's to motorcycles to my Subaru, I can feel (smooth) and hear (quieter) the difference. Moreover, when friends comment on how good something of mine runs, it reinforces the fact that Amsoil is an intricate part of my maintenance routine with all engines in my family.

I haven't tried the new boosted formula yet but I have had no problems with the product the only thing I would like to see improve is the container I keep a quart bottle in the car with me due to a small oil leak I have and the bottle top leaked oil on to my carpet. This is nit picky I know but it's the only thing..

Bought some XL to take me to April, which is normally when I do my annual oil changes with the Signature Series. The XL works great, flows excellent in cold weather, etc. I've pretty much gone to using Amsoil in all my vehicle's, in every place lubricant is needed, from trans fluid, gear oil for the diferentials, grease, ect.! Most everything i buy for the vehicles comes from Amsoil!

I drive about 1000 miles a week as a Courier and I want ed an oil that would last up to 10k miles. So I gave Amsoil

When I bought my 2004 Subaru Impreza WRX back in 2004, I wanted to use the best motor oil around to keep it performing at it's peak. I tried other brands of synthetic motor oil first and then found out about AmsOil while looking online to try and find the best. I then asked some co-workers about it and started to understand more about the
company and the products offered. I signed up for a membership and ordered the regular synthetic from AmsOil and I could feel the difference from the other brands while driving my WRX. I eventually went with the XL product and extended the oil change intervals to between 5,000 - 7,000 miles on my car. My 2004 was totaled recently in an accident and now have a 2017 WRX which I plan to continue treating it to AmsOil XL synthetic oil while I have it.
As long as the prices for products remains competitive, I know what I'll be buying for my cars.

I use this oil in my 2007 Hummer H3 along with other Amsoil products, it has improved performance and fuel mileage. Also in a Hummer H3 the intake and emissions design causes the throttle body to get dirty, this causes performance issues. Amsoil has reduced the times I have to clean that. Give Amsoil a chance and you will believe.

Used this product for my 2008 350z Roadster, this is the second go runaround with this product. I have noticed my engine runs smother and idles better (66,100 plus miles). I used other brands of synthetic oils on my prior vehicles (Mobil1, Royal Purple, Castrol) but by far I am the most satisfied with Amsoil. I want to use the best product available and so far this is the best to me until otherwise. I have not performed any lab test or chemical analysis but real life driving. Also I need to mention better gas mileage, how I know I am getting better gas mileage? I know because I do not fill my tank as often (i use Premium that is what Nissan requires for maximum performance) I wish Amsoil had a high-performance filter like K&N or aFE, I would buy it too

I've been using Amsoil for the last 250,000 miles of driving between my current and prior car. I just wish I'd discovered it sooner. When I first switched to it, I kept careful MPG records and found that the increase in mileage with Amsoil more than offset the higher cost of the synthetic usage. What's more important, oil consumption in both cars between oil changes (6,000 miles on average, which I arrived at as a time for changes based on lab analysis of the used oil) has been zero, even when my last car was up at 200,000+ miles.
