Agreed, most dudes have been nice. Only two dicks so far and one got banned.
There are two kinds of snake oil. There was the 19th century folk remedy from actual Chinese water snakes where the chemistry made sense as pain relief. Then came the type that fools people.
Admittedly influenced by fleet and enterprise operations experience plus age I stick to a manufacturer's terms during warranty period and often beyond. Also get service performed at the dealers. It has never been any significant expense and has had times when I got coverage past warranty or the dealer on my side. The point of the fleet and work ops was that greater scale was showing more instances when it makes a difference.
I should point out that my Taco just rolled 30K miles, and It has become quite a bit more quiet staring around 24K miles. I barely hear the injector pulses anymore as I once did.
Yes, and No. It's not an engine flush in that sense, however it is a "cleaning" oil, and most importantly, it keeps, or will clean clogged oil control rings. Once those are gummed up with returned crankcase gases via the PCV system over time, your engine will suffer from excessive oil consumption, and cylinder "wash-down" where the fuel coming into the cylinder for ignition purposes slides past all those rings and washes down your cylinder walls, scoring pistons, walls, etc.
1. I can find no place that states Amsoil complies with ISLAC GF-6A. There are numerous references to meeting some of the individual specifications requirements but not the specification as a whole.Man I love these statement but I guess I'm just as foolish to keep posting when I read these.
So 1 "Amsoil will not state or guarantee their products meet or exceed the manufacturers specifications*
To answer this um yes they do as I've stated it's all over Amsoil website. Does it state Toyota, Honda, North America blah no. Does it state the specs yes.
2 the certification to " state this oil is certified to meet blah spec" is a pure money grab that Amsoil can not only afford but requires to pay.
3 " If there is an oil related warrenty issue, using products that are not proven to meet the specifications would make it easy for Toyota to not accept the issue and void the warrenty claim". Have you ever heard of this, filed any claim of warranty claim, understand the process of a claim, or have read a refused "claim" by a manufacturer? If not listen up. Any and all said claims are claims that the Manufacturer has full right to deny at any time, e.g. if you do your own oil changes this too can " void" said warranty. When I say any and all I mean any and all at the manufacturer/dealers discretion.
4 in short don't drink the snake oil FDA red #5 is not good despite them saying it is.
2hat happened to those guys anyways.
