For automatics, a cooler will do more good then using any fancy fluid

 

Agreed! Coolers can prolong trans life by keeping fluid temps from getting too hot.

 

I am excited to try full synthetic and see what mpg change I will get

 

If it's more than 1 mpg the difference is due to placebo effect. Controlled lab studies put the difference at 3% (sorry don't have a link).

 

The performance increase is about like switching to premium gasoline, none!

 

I really can't remember ever seeing a post resurrected after 10+ years......

Automotive engine oil technology has really made great strides in both snthetic vs conventional oils- especially over the last 10 years. I would ignore what members did for oil changes 10 years ago and look on the internet for published info on what the petroleum companies are publishing for recommended oil change intervals. Current info should also be researched from oil filter manufacturers as to how many miles oil filters can go- especially with synthetic oils.

Just my two cents worth.

 

@irontmp I change my oil and filter very 3,000 mi. I use Amsoil 0W20 Full Synthetic and a Honda OEM oil filter (the ones that are made in Japan).

 

One of the few people on this thread I want to buy a used car from. It's all about keeping the carbon build up out of those low friction rings.

 

"Honda recommends" . . . ?

That's not in my Owner's Manual. What is your source for this recommendation?

 

I've never had a car or truck with a oil life % before and I've always gone 10,000 miles between oil changes using walmart supertech full synthetic 0w-20 and Fram tough guard oil filters and I don't plan on changing a damn thing. It has worked out fine for my other cars (toyotas).
