Customer Ratings & Reviews

Hi - I am running this is high mileage jeep (Florida) that per my Torque Lite / app & module the jeep is running 4-7' cooler since using this oil. the only way is less friction. again live in FL and on June day I changed oil I ran my jeep around block to warm oil before change and after oil change took same route and some highway and was actually several degrees warmer (late AM till afternoon heat) and just love this oil. NOTE - IF you live in cold areas I personally would not run 10/40 as 5W-30 flows better when cold. I just have always ran thicker oil in summer heat in FL

This is my second year with this product in my SUV's and they are running like new.

Good

Best oil in the business in my opinion. I've been using for years. You get longer change intervals, no sludge and great performance!

Great oil, even after 10,000 km engine runs smoother

Great oil in my V10 Ford powered motor home.

The best! Hope the product is never discontinued!

Great oil I use it in my 15 wrangler, no complaints.

out standing

I use this oil exclusively in my personally owned '03 Chevy 2500 and '04 Chevy Tahoe. The 2500 have around 250k and the Tahoe at almost 275k. Both engines run as smooth as butter.

Excellent oil love it

Goes in my supercharged wrangler and my wrangler loves it when the oil is changed and I go 6k on change intervals.

I love Amsoil products ... the XL 5W-30 Synthetic Motor Oil is a great product. I especially like the Wide-Mouth bottles ... no lag time or slow-pour with these great Wide-Mouth bottles. Every brand of oil should use these Wide-Mouth bottles. Keep up the great work, Amsoil.

This is what I use in my truck

Great upgrade to oil changes in our 2003 Envoy.

Amsoil has always products that I trust! This is spec viscosity fits all three of my vehicles. Keep up the good work!

Used for my Harley, won't use anything else.

Best car insurance policy anyone can get

Amsoil offers best protection at reasonable costs. Don't have time nor $$ for car purchases every 3 years. Get the best car and keep it maintained with the best product.

Great oil! Use this in my '17 Silverado and it works flawlessly! Recently had the engine checked over and when they pulled the valve covers it still looked like a new engine! 10/10 will buy again
