Disclaimer, when I say "synthetic" I mean actual synthetic, PAO Group IV. I don't consider the rest to be real synthetic.
I own a good number of used vehicles. Only every bought two brand new ICE vehicles, a Ford with a Powerstroke in 2020, and a Toyota Corolla in 2005. The Corolla was totaled with 330k miles, still ran like new, had a small rear main seal leak, only one oil change per year for 14 years, average 24k miles per year. Otherwise, I have two passenger cars, two semi trucks, a tractor, lawn tractor, various small engines, a school bus, and a forklift.
I switch all these vehicles to Amsoil at some point after I get them.
Some times, I can't tell any difference. But often, there is a difference. And I have just experienced the biggest difference I've ever felt.
I bought an old forklift with a propane fueled engine, and it was real sluggish. Slow to start, long crank times, smoked a bit, an old propane forklift, if you know you know. But when I got it it had fresh oil, so I didn't change it for a year or two and just ran it as it is. Then I finally decided to change the oil.
It was a huge difference.
Instead of cranking for 15-20 seconds to start, it now cranks 3-6 seconds. While still sluggish compared to a car engine, it is now so much more peppy than before. And it smokes less. Still smokes, but less.
And this is the biggest difference I've noticed in switching to synthetic, perhaps two dozen times in many various vehicles over the past 25 years since I've been using Amsoil (and other synthetic options). They start so much easier.
I have heard many people complain about how the 6.7 Powerstroke takes so long to get oil, and I have seen videos hearing the engine clack before it gets oil. Not mine, I have never heard that. And my truck usually goes 1-3 weeks or longer between starts. It's a work truck, it only works. Not a daily driver.
And the difference in small air cooled engines is more stark. Since putting them on synthetic (and fuel preserver) they almost always start immediately. I have a pressure washer that sits in the storage shed for 6 months at a time, gets used a handful of times a year, goes up to two years with the same fuel in it, and it starts up every time. For small engines, you can't do better than synthetic oil, and fuel preserver 100% of the time. All my stuff just works. I have a rototiller out in the greenhouse, just sits there in the sun all year, gets used maybe twice a year, I can walk out there right now, flip the choke on, and it will start first pull.
No, I am not an Amsoil dealer, and I don't care if you use Amsoil. Other synthetics work too. But I have been using Amsoil for 25 years and I have found nothing better. It makes a real and sensible difference. That's my experience.
