gas octane? is 93 worth it?

fuel injector cleaner? does chevron techtron(in a bottle not gas pump) work?

standard(nonsynthetic) motor oil? do brands matter? whats best?

any good oil or gas additives? (slick50, duralube type stuff?)

whats the best tranny fluid?

I use whatever octane it says in the owner's manual. Prior to putting on the S/C I used 87 Octane (like it says in the book). Since the S/C install, I use the 93 Octane. I will throw in a bottle of the Techron once per month and use BG44K about every 10K-15K miles. All my other fluids (diffs, tranny, oil) I use AMSOIL.

i use 89 usually, but sometimes 87 when prices are high. no one needs to put 93 in their runner.

Avoid any of those fuel/oil additives,nearly all are a joke,just use a good brand name oil whether it's dino or synthetic.

I use a can of BG's 44K in my fuel system once a year,it is kinda pricey but better works.

Unless you have a Supercharger.

One additive that you may wanna look at is Auto-RX. A couple of folks here are running through the process now:

89 octane here, amsoil oil, and I'm going to use BG44k next fillup.

In your vehicle, I'd just run the cheap stuff for gas (87).
Yes, the Techtron does work to clean the injectors so do use that.
I use dino oil but many are using amsoil brand with much success.
I second the Auto-RX, I am not using it but from what I have seen it works very well.

lee

of course. i meant stock runners.

Here in Colorado there is no such thing as 93 octane (high altitudes). I use 87 or 91. I also put a can of BG 44K in once a year. As far as fluids plain Valvoline motor oil and BG oils for the tranny, and diffs.

For me - High octane, Mobil-1 in the motor, Amsoil everywhere else.

Techron in the bottle is the way to go.

As for non-synthetic oil I'd stick with a name brand. Castrol, Havoline, and Valvoline are good choices. But why use old technology when you can get Amsoil with 7500 drain intervals??

I use 87 in everything I drive.

I run pennzoil w/ schaefers moly additive. (the additive is not a joke, Ive used it in several vehicles and its never failed to extend the life of the oil. As in when they would start to use a little oil around 4k miles they now run to 5 or 6 without using a drop)

We used to sell the heck out of Techron cleaner with lots of positive results.

I do not care what anyone else says.. Barrymen B-12 is good poop...I add it in 2 times a year.

I recnetly changed to 89 and just did the Techron treatment. I was getting a little knock around 3K. I haven't driven it enough to see if it helps though... :pat:
