engine while running Amsoil vs would I formally Grande I run Angela and all my four-wheel and two wheeled vehicles also run many other Amsoil products I can't say enough about it.

Top quality oil product! I use Amsoil in all my vehicles both on and off-road. It's outstanding how Amsoil's synthetic blend oils stand up to thermal breakdown. I typically replace my vehicles engine oil after 10,000 km...and it comes out darn near the colour it went in. Even in my Duramax!

Best product on the market. I've used it in my Honda CrV for 13 years, I wouldn't consider using anything else. No issues with the engine and the oil comes out clean! Not sludgy like other oils.

This oil is really good, I use it in a Nissan car. Before the normal oil my car would burn in a part every 1000 miles. Now with this one it burned the same but in 1900 miles and using the air conditioning. So this oil is really good to use. I really recommend.

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

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.

I switched my vehicles to full synthetic after trying it in my motorcycle. I now buy by the gallon and switched everything to synthetic oil, differentials, transfer case, etc. Gallon containers are convenient and economically priced. I'm amazed by the amount of residual deposits that are removed during the first switchover oil change in my vehicles that are were quite honestly, very well maintained.

Reviewed by John:
Look my friends, if you have searched for the best oil on the internet for countless hours as I have, AMSOIL is truly the best you can get so stop searching and just get it. I have tried many, many other brands and nothing I have ever used even comes close to AMSOIL. I use AMSOIL products in all of my small engines, lawnmowers, weed eater, pressure washer, generator, as well as my personally owned vehicles. This stuff is the real deal and doesn't evaporate, and does just what is it is supposed to do, that is, protect your equipment/vehicles. Don't waste your time and money looking elsewhere, just give AMSOIL a try and you wont use anything else. I have been down the road looking for the best protection and have finally found it in AMSOIL products. Thank you AMSOIL.

Fantastic
Use this oil in our motor home, three cars, it's just awesome! We live in Anchorage, Alaska, and the cold winter starts are great-we don't hear any knocking when we first start the vehicles in the morning, and yes we do use the motor home in the winter to go snowmobiling-and the temperature at night can go low as -30 degrees (it did happen), the motor home started with no noise coming from the engine-quiet. As to other conventional oils you would hear cold oil knocking until until the oil warms up, NOT AMSOIL!!! And the mileage-we saw an increase in miles to gallon ratio. I'm will always stick to AMSOIL!!!
