Use this in my 2002 Dakota works good. I will us one quart of Z-rod and 3 quarts of 10w-30 signature series and it runs like it was back when it was new

Used Amsoil Break in oil on my 355 SBC Ran 500 miles changed over to the Z-Rod oil and now have 2,500 on engine runs great .No lifter noise great oil Psi This is some great oil

Just the perfect oil for my old flathead V/8 Ford. Great engine protection!

Very convenient, don’t have to mix any additives, it’s all in there for my 64 Thunderbird!

There exists no comparison between the Z Rod oil and regular conventional oils. My cars engine need zinc and Z Rod has just the right amount. Change oil once a year and it does a great

I use zrod 10w30 in my 1948Chevy BBC

Z-ROD is exactly what I need to keep my original 1966 V8 going strong. It spends a lot of time in storage and Z-ROD is exactly what I need to fight moisture/rust and fire it up when bringing it out to drive. The Zinc additive is the best part and protects my old engine components. Wouldn't buy any other oil!

worked great in my 540bbc race motor

Me and my 3.5l bolt on v6 absolutely love Dominator. Mind at ease when spinning motor out north of 7000 rpms. Then its all about maintaining oil pressure.

I changed the Viper from Mobil 1 and immediately saw a difference. The car has both engine coolant temp and oil temp gauges. With Mobile 1, they were always within a couple degrees of the same. With the Amsoil, the engine oil dropped 6 to 10 degrees. The engine makes about 825 HP. The Mobile 1 was always discolored upon oil change. The Amsoil is still red when I change it, at twice the miles.

Awesome product at an awesome price! Thanks!!

I’ve watched a lot of oil test on YouTube and ams oil beat every other brand tested, some by a large margin- volitility, lubricity,cold flow, etc. Fast delivery was a plus.

We have a Turbo 944 Porsche strictly a track car at 13 pounds of boost it’s doing 345 Hp at the wheels at 20 pounds 460 , a lot of stress on a four cylinder, I lower the pan a pull the rod bearings every 100 hours , since I’ve been using the Amsoil the bearings look like there brand new .

I use nothing else in my classic car.

I noticed right away as soon I poured this in my truck even the color of it yells quality I’m very satisfied with it so far and I recommend

I started running Amsoil when I purchased my first Chevy 2500 with the Duramax engine in 2007, I became a Preferred Customer and when I need oil, Amsoil is what I buy, run the racing oil in my 2 camaro Hot Rods, run the Signature Series oil in my Honda Accord work car, purchased a new 2020 GMC Denali 2500 with the Duramax and at 2500 miles changed it to Amsoil Diesel Oil, also run the racing Transmission Fluid in my 2 hot rods and my old Duramax and will be changing the transmission fluid in my new truck in a few more miles, also run the Amsoil gear oil my hot rods and want to change my truck gear oil to Amsoil soon, have had no problems and hope that the Amsoil is going to make everything last longer, also run Amsoil filters on everything

Excellent quality oil, perfect for a performance small block Chevy engine with flat tappet camshaft.

I started using Z-Rod motor oil in my 68 Charger last year. I have tried many other motor oils in my 440 engine. These big block engines create a lot of heat and are pretty tough on oil. With the Z-Rod oil, I find my engine runs cooler and just seems to run so much better. It's not uncommon for big block Chrysler engines to be topped up with oil every so often but with this oil, my engine doesn't require a top up nearly as often. This is my second case I've ordered and will run nothing else in my classic car.

I have used Z-Rod 20W-50 in my 383 Stroker motor since 2014. This engine is on my Airboat and will often get run very hard for extended periods of time. The motor runs fantastic and does not use any oil. I would highly recommend this oil.

Have been using a lot of different types of oil but I gotta meet this one here is number 1 this dominator is an awesome product
