Greer overall product.....best oil on the market, won’t use anything else!!

Great oil, best on the market!! Use in my 06 Lincoln Mark Lt and in my BMW X5 Turbo!! Worth every penny, great American made product, won’t use anything else. Thanks amsoil

I've been using Amsoil OE for many years now. It works well for me since I have multiple vehicles. The price point of the Amsoil OE fits my budget for a really great oil. I will stick to using the Amsoil OE!!

This is my first time using Amsoil and they have great communication, shipping speed & well packaged. Now that I think about it I have a 09 GMC Sierra with a 4.8L & it used to have a lifter tick sound but I haven’t heard it since I changed my oil to this OE Synthetic.

Great lubricant. My engine even sounds different. Change every 10,000 miles. The difference in my car is amazing. I will continue to use this oil in all of my cars.

my first year using Amsoil products in my car and small engines. so far I cant complaint .I really notice the difference and will continue to use Amsoil products.

Ideal for stock cars or trucks

Best oil money can buy, use it in all my vehicles and power equipment. American made American proud to use. Recommend to all my family and friends!!

Love Amsoil its the BEST. Mahalo

I have ran mostly AMSOIL for last 20 years, I have been preferred customer since 2009. I only switched once. I put Mobil 1 Full synthetic in both my V10 Motor home and my 5.0 V8 and noticed a louder valve train immediately. I would cringe every time I started either one up they sound like there was no oil in them. It was so bad I changed the oil out extreamly early and went back to AMSOIL. Maybe consider a AMSOIL sticker bucks program, trade 20 stickers for a hat or something

Until this year, I always ran Pennzoil. I had always liked Amsoil, but it was difficult to get, and it was cost prohibitive compared to off the shelf oils. Since then Amsoil has continued to deliver a great product, and prices are very competitive, and most of the time better than competitors when oil change intervals are factored in. I used Amsoil OE 5w30 in one vehicle initially (2001 Suburban, 250,000 miles), which resulted in higher, more stable oil pressure. I have also extended oil change intervals to 5,000 miles over the 3,000 I was doing. I have since started using OE 5w30 in all of my vehicles. This is an outstanding oil, I couldn't be more satisfied.

The full synthetic oil is great. However, on a cold start the engine (5.3) is noticeably noisier. I switched from Mobil 1 high mileage full synthetic, which seemed to have kept it quiet. Also, at high RPM the truck seems to run a lot smoother with the Amsoil.

Purchased for a friend since he didn’t have a membership so no personal experience but if it’s anything like xl or signature series it’s protection and burn off rate is far superior to anything you can get in regular box stores no matter what the brand of oil only complaint in my opinion is that it should maybe have a slightly longer than 3000 miles protection but $5.??a quart with membership and free shipping no complaints here.

Gives me peace of mind to know this oil out preforms the factory fill. There is a lot of value for this competitively priced synthetic oil, and the containers don’t tip over easily.

No issues so far.

Been running this in my Subaru for 50,000 miles and I’m super happy. Great product

I've used Amsoil products in my vehicles for around ten years. I like the oil change intervals and the quality of Amsoil.

just switch to this oil a week ago, had been running 10w-40 mobil hi mileage. Put in 2010 avalanche with 110k on it keeps lifters quite on start up, also changed 03 Tahoe with 197k on it. Valvetrain operates smoother. Will continue to use
