I use XL 10W-30 in my 1997 Buick Riviera Supercharged 3.8 V-6. It's now a weekend cruiser and the miles do not ring up so fast. Each spring a new oil and filter and the Riv is ready to go for the Year.
Bottom Line
Yes, I would recommend this to a friend.

I love amsoil in my opinion it's the best you can get.
Amsoil is the best oil I’ve ever used in any vehicle. It’s durable, reduces friction, wear and tear, and lasts well beyond typical oil life. This oil never breaks down. I highly recommend it for any vehicle of any age or mileage.
Had been using Pennzoil Ultra in a particular car and decided to change to Amsoil Boosted 5w-20. After changing my oil and listening to the engine I could tell that Amsoil Boosted is a better oil.
Amsoil is one of the best oils I have found that lasts as long as it says on the package I live in a place where the weather changes a lot and so far I haven't had a problem with it or the shipping ups has it at my door within 3 days. I have used it in my jeep for years and my new gmc as well as my toy's. In short why look for something else when I get good quality and it works well. Ps hope this helps someone else out.
Bought my car brand new with 8 miles on it. So besides what oil was in it, and the free oil change. Amsoil was the only oil that I baught. Runs smooth, good gas mileage, and really nice changing oil every 12,000 miles. I drive over 20,000 miles a year in this car.
