I started using the XL 5W-20 when my daughter bought a used 2009 Kia Sedona which calls for 5W-20. I did an initial Amsoil Flush which produced some evidence of carbon deposits in the filter pleats. I've continued with XL over a number of oil changes. The Amsoil synthetic continues to breakdown carbon deposits, so the cleaning effort continues. By comparison, my own cars, which have been on Amsoil for years, show filter pleats that are significantly cleaner at oil changes - basically just a brownish color change instead pleats with accumulation. It continues to improve!
I would 2005 Subaru Legacy GT with 120,000 miles. This oil is like magic in my motor. Although my seals and exhaust valves were replaced at about 105k miles, due to the nature of turbocharged engines being notorious for heat and burning oil, I was adding at least 3/4 of a quart every 2000 miles before my oil change with Royal Purple. But, with AMS Oil XL Boosted I’m only adding about 1/4 of a quarter at about 2,500 instead, and my oil stays remarkably clean at 3,000 miles.
I like all the Amsoil products. They protect all my equipment. Use it in my Farm Tractor, ATV, motorcycle, Lawn Tractor, snow blower, chain saws, rototillers, etc.
Great oil been using it for a few years never had an issue with boosted applications. K24 Borgwarner S366 on E85 holds up well with E85 would recommend!
Here is my review.
I have been a paying customer for more than 3 years.
I own 2 Mazda CX5's and have purchased a lot of oil & filters, and paid for my membership.
You used the Covid excuse to delete the required oil filters for this car without any options, forcing me to buy filters on the street while still paying my membership dues. Thanks!
Bottom Line
Yes, I would recommend this to a friend.

Beat oil I’ve ever used. I’ve put over 200,000 miles on my truck and it’s still running strong with no problems. Would recommend this product to everyone. Plus you don’t have to change oil as much.
Bottom Line
Yes, I would recommend this to a friend.

XL 5W-30

I have been using the XL synthetic in our Ford F-150 & Explorer since it was introduced and believe it provides great protection as well as no oil leaks after switching from Ford's synthetic blend.
My nine cars all have Amsoil without any failure. It’s difficult to evaluate a motor. Blind product as long as no failure. What I really like is the long change interval, since most my cars sit, and get little mileage.
