I would file a formal complaint with Toyota and maybe even the BBB

They are like a Harley-Davidson dealer, they don't want you to use AMSOIL, AMSOIL saves motors, AMSOIL will cost the dealer lost revenue. It doesn't matter if it's a motorcycle, car or truck dealership, they make the most money on service & repairs.

I disagree, Toyota has built a reputation of quality and reliability, I don't think they are conspiring to cause problems so they can make money on you off of repairs. That would be a pretty poor business model!! Others have tried and failed at miserably.

I am not referring to Toyota, I am referring to individual dealers. They have a vested interest in having you come back again and again and again. They make the most money on parts and service. Think about it, how many want you to keep driving your truck? You are the only one; the dealers want to sell you a new truck. All you are to the dealer is money in the bank.

I'll give you a for instance. Neighbor lady has a Rav4 about 3-4 yrs old now. She drives 100 miles to the dealer to get her oil changed because she fears warranty problems if she does not. She told me they told her that when she bought the car, salesman I presume did that. That is unethical of them to do that, coerce and intimidate her like that.

I hear ya...but..

Like John Wayne said: "Life is tough, it's even tougher when you're stupid"

(I'm NOT calling YOU stupid)

My free service has ended at Toyota dealership so I am just beginning to read up on oil.

Could someone explain to me or post up a link to the claim that 30 is better for the longevity of the engine and 20 is better for the mpg? You would think that less viscosity the oil has better mpg and less wear the engine will experience. Are you saying that 20 is too thin for hot weather or heavy-towing/hauling application?

IMO

30 is thicker therefor has better film strength but also causes the engine to work harder due to increased viscosity i.e it's harder to flow the thicker oil and creates more resistance but not more friction. The 20 is thinner and flows easier, less film strength and less resistance means better fuel economy, some would argue that it also lends itself to more friction.
