I will continue to use Amsoil in my vehicle applications

Overall, The 5w30 SS oil I'm using seems to lubricate amazingly well. No complaints to speak of at this time however, this is the first time I've ever used this product so looking forward to getting an oil sample test done just to see how things are looking at the 20k mile mark. I'm skeptical of extended drain intervals so look forward to how this oil tests at next service. I WOULD like to see more content of Amsoil vs Redline products though.
I've been using Amsoil since 1998. I've had to replace the intake manifold gasket on past pickups, when the mechanic ask me if I cleaned the inside of the engine before bringing it in I said no, I use Amsoil full synthetic. He said well the inside of the engine had absolutely no carbon buildup. He said that was the cleanest engine he had ever seen that had 110,000 miles on it. From that day forward he too was a Amsoil customer.
Bottom Line
Yes, I would recommend this to a friend.

So far so good

I drive a 2009 HHR with a 2.0 NA 4 cylinder engine approx. 100 miles a day and have 160,000 plus for mileage. Economy comes in many forms in this case fuel, oil and tires are my biggest expenses and ones that I can somewhat control. We had a cold spell not to long ago of real temps -25 and colder. The HHR still has the original battery and with the Signature Series 5w/30 it cranked right up with out a problem. Next step is to submit an oil sample same time as the factory algorithm says to change oil.
The truck runs great and uses no oil at 130,000 miles
Bottom Line
Yes, I would recommend this to a friend.

A++ lubricant

This oil does what they claim it can do. I normally try to change my oil at around 12000 miles, but sometimes if I'm too busy it goes much longer. At the last oil change, I changed it at 25000 miles. No problems whatsoever. The dipstick oil level was still normal after a year of use. The Signature series oils are worth the extra money. I also use the diesel oil in my 06 Duramax truck. It's about to hit 400,000 miles and not a single problem.
Now this may sound negative but it's a positive. I bought the 10W 30 for my 1998 Jeep TJ 2.5 with 250,000 miles on it. Amzoil really cleaned and lubricated my engine really well. I dont recommend going to a synthetic motor oil if you have high milage and you did not you synthetic oil prior to because this oil cleaned my engine up but I developed a leak. But in retrospect I'm am going to use only Amzoil in it when I rebuild the engine. Went back to Dyno oil for the time being.
have used Amsoil for the last 15 yrs. never any complaint with it the only way I get my lawn tractor with the snowblower started in the winter starts every time
I have changed both vehicles over to Amsoil in the engines and the differentials,transfer case and transmission on My pickup and will soon put in Amsoil coolant.
Bottom Line
Yes, I would recommend this to a friend.

Great oil for your vehicle. Wouldn't use anything else
I have used Amsoil 0w 30 in my 1998 Corvette and now I have 213000 miles on it and there are no unusual engine noises. I change my oil once a year. I have three boats 2 Corvettes,1SUV and a motorcycle all use Amsoil products. I virtually have had no powertrain problems. I use nothing but Amsoil and will continue to do so. I appreciate Amsoil technical papers as they show the science behind these outstanding fluids and are useful to convince others of the merits of Amsoil.
Bottom Line
Yes, I would recommend this to a friend.

I have been using Amsoil in my vehicles since 1986. After having to change a timing chain in an earlier vehicle...it was clear ( internally ) how good Amsoil actually is. The chaincase was as clean as if it was just made. That vehicle continued on to + 260,000km with no oil leaks or other loss. Amsoil....I am a fan for life!
I use Amsoil in all my vehicles, and I have many. From my Shelby GT 500 to my ATV and lawn mower. Best oil you can buy!
Bottom Line
Yes, I would recommend this to a friend.

Been using Amsoil Signature Series 5w20 for over 18 years and have been extremely happy with it. I go 15000 miles between changes and never use more than a half quart between changes. It's the BEST.

Always satisfied with Amsoil

I use this in both of my vehicles; one specs 5W-20, the other 0W-20. It gets down to -15 degrees where I live in upstate NY and I depend on Amsoil to provide effective lubrication at temperatures where other oils struggle to perform. I generally put over 250,000 miles on each vehicle, and have never had one consume any Amsoil. Totally satisfied.
