Fuel opinion and additives
 

Guys what is your personal opinion on fuel additives ? Here's why I ask..I have always used Marvel Mystery Oil. An old mechanic told me when I was a teenager to use it and I always have,, I do know I sold a chevy truck that had a 350 SB. when I sold it , it had over 400K and never been torn down , ( I actually sold it to a friend) he later changed the valve cover gaskets and said the inside of the engine was spotless . All I've ever used was Mobil 1 and Mystery oil.. I sold him the truck 5+ years ago and it still runs strong. starting to use a lil oil but still....... So I've also been putting it in my fuel in the ZR.. I'm just hoping it will counter the effects of the corn syrup their adding to the fuels.
Just wanted your opinions..

Hey Paul, I'm using the AMO hi-zinc . From what I can see it is the best .. I'm basically using the marvel oil in the fuel .. Thanks for the info...

not to hijack the thread, but where can one get the zddp additive to add in? I don't think the oil I put in has enought zink in it

Kevin, I've read a few articles on the additive and a lot of people are saying the high detergent oils won't allow the additive to adhere where it needs to. I've switched to Valvoline vr1 10w30. It's the correct weight and has enough zddp. Best of all Napa and advance stock it. With that being said the best price for the additive is eBay or Amazon.

I use Engine Armour in all my Corvette's. In 1968 427/435, 70 LT1, 70 L46 and my 1960. Have not tried in my ZR1. Just bought it a couple of weeks ago.

Best is to buy the oil with it in there already - to avoid chemical incompatability problem (this according to a write up I read by a leading oil manufacturer.)

The Amsoil AMO 10W-40 is one, but there are others.

I have used MM oil in LS1, LT1 & LT-5 and especially the RX-7 Rotary.

For Storage, I was running a mix of:

Ethanol Free Fuel High Test Fuel
Chevron Techron
MM Oil

My Tune is from SGC & Haibeck. The 16 injectors are OEM original.

I noticed that if the fuel sat for a few months. It formed a few odd little red dots in the fuel. It really was not big deal. My only guess is the MM had a reaction with Chevron Techron or I might have had a Lucas in there.

Regardless, I think running some MM through your fuel is a good idea. For sitting cars over extended periods of time, I use the following:

Ethanol Free High Test Fuel
Chevron Techron Inj/Fuel Cleaner

I empty the tank driving or drain it manually every 90 days.
