Bubba, you are wrong in your assumption.
My feelings weren't hurt at all. Honestly. Even though you didn't employ any of the online abbreviations or gremlins typically used to telegraph a humorous or joking post, I took your comments in the spirit of fun, and used those gremlins in my posts to indicate that I was funnin' ya right back.
Don't make me stop this car..............grrrrrrrrrrrrrrr
Will, the problem with car/truck oil change intervals is there are so many variables in operation.
If you have a car that's only doing 1500 miles every eighteen months or so, you'd be changing the oil at least every twelve to eighteen months, regardless of blend.
If, however, you were doing the miles my SO was at one stage towing horses to the big smoke with her Nissan, (5.5 hour trips minimum) I was doing oil changes every two and a half weeks when under warranty (5000km OCI specified in a 4.2 litre turbo diesel)
As soon as it was out of warranty I started using Delvac 1 (I had a few oil tests already under our belt using a very good mineral oil) and was able to stretch those oil changes to 20,0000km with less wear metals present, soot under control (barely any higher than @ 5000km) and in front financially, all while the thing was being worked hard.
It's not doing those sort of long trips any more, so I've pulled the oil change intervals back to 10,000km. all this with an oil that didn't comply with Nissan specs, it was too good
BTW, that mineral oil I was using, one of Fuch's blends, would have been fine well out past 10,000km, maybe at least 15,000km without breaking into a sweat but Delvac 1 did deliver better results at the time. Bear in mind all the oils i was using back then have been reformulated a couple of times at least since, and how they run now may be totally different to what I achieved then.
Amsoil's big problem isn't even so much their own advertising, it's the evangelical rhetoric pushed by many unknowing dealers
Well put.
My experience with Amsoil started 25 years ago, when my then FIL was a dealer in N.D. He was an Air Force pilot and a motorhead, and he ran Amsoil in all his vehicles, as did his children, and, eventually, me. I haven't always been able to afford Amsoil in the cars/trucks, but when I got heavy into 2-strokes several years back, Amsoil was the natural choice, one that I had confidence in.
If you strip the marketing hoohah away from any product and just listen to the people who have been using the product themselves and weigh what they say against your own barometer of life experience, you'll get a better sense of that product. It's no different whether you're talking chainsaw oil or hand lotion, hunting rifles or fishing rods.
People cocking off "knowledgeably" about products they have never used, or have barely used, are endemic in online informational forums such as this. Even an oil expert doesn't know how an oil is going to run until they run it. I listen to the smartest of the oilheads even if they haven't run Amsoil, because that's their field of expertise. But in the end I place more value on the opinions of those who use the product in their day-to-day work.
Just the way I'm looking at it.
