I currently have almost 90K on my car.

1. Engine - Changing from the Valvoline 5W30 engine oil I currently use to Amsoil ASL 5W30 Sythetic.

2. Transmission - Changing from Toyota Type IV ATF to Amsoil ATF Sythetic.

3. Rear Differential - Changing to Amsoil Gear Lube Synthetic for the rear differential; BTW the diff (LSD) is brand new.

After reading and searching through CL I gathered that Amsoil sythetic oils work wonders on our cars. Please advise if there is anything that I should watch out for when changing these three fluids over to synthetic. Thanks...

Just curious......what will you be paying for the various Amsoil products? Isn't the Lexus Type IV tranny fluid synthetic?

Not sure I'll probably just go to a local auto parts store and pick some up at their price. As far as I know I don't think Lexus/Toyota uses any OEM synthetic fluids; I could be wrong though...

I think the Type-IV is synthetic. Or at least according to the guy at the Toyota parts department said. I just got 4 bottles this week to do a flush on my car. I specifically asked him if it was synthetic and he said yes. I also asked what the recommended service interval was and he recommended 30k even though the factory states that it can go for 90-120k.

Rock-a-lex, don't use any of the local auto part store fluids. The transmission will not shift correctly. Use the Toyota Type-IV fluid from the dealer. Usually about $3-4 a bottle so it's not really that much more than the Dextron you will find at AutoZone. The other option is to use Amsoil ATF.

Thanks Jeff...I'll check out the Amsoil ATF. I'de like to fully convert to all Amsoil products. As far as the engine goes does it matter that there is 90K on the engine that only used regular oil? I want to switch to synthetic.

ROCK-A-LEX i HAVE A 97 ls 400 WITH 110000 MILES I DID THE FULL AMSOIL
TREATMENT ABOUT 10000 AGO, ALL IS GREAT, BUT YOU NEED AFULL FLUSH ON THE TRANSMISSION. MY WIFES CAR IS A 99 GS 300 WITH 44000 AND I HAVE ALL THE STUFF TO DO HERS, I THINK THE AMSOIL IS WORTH THE PRICE. GO ONLINE OR THE YELLOW PAGES AND GET A DEALER YOU CAN TALK TO ABOUT THE AMSOIL, AND GET SOME INFO FROM HIM JIMANDBARB

I too would like to switch over to synthetics. Everyone I ask tells me something different. Some say don't do it if you have been using regular oil. Other say it doesn't matter. Thanks for posting this Rock-a-Lex! I am definatly going to keep an eye on this one!
