What octane is best, and why

[FergusonTO35]

In other words, do what works for you!

As an engine wears, combustion byproducts slip past the rings and valve guides. This causes the oil to load up with contaminants faster than a new engine would. People can do what they want to. I really don't mind frequent oil changes, gives me a chance to inspect everything.

In all honesty if we could stop friction in motors they would never wear out. Moly is a good friction fighter. I've got 327k miles on my pickup and change the oil ever 5 to 6k miles.

Are you using a moly supplement?

Just started this oil change. My brother has a pickup with lifter chatter. When he uses moly it gone.

Just realized the way that post was worded made it look like I used moly for all those miles. I have already noticed the engine is smoother.

It is rather fortunate that it's cost prohibitive to ship ethanal fuel to Alaska....all our fuel is "corn squeezins" free.... If it wasn't for government subsidies ethanal fuel would be largely non-existent in the US.

I run 87octane in all my gas engines. Don't own anything with high enough compression to warrant otherwise.

Thats the short and the the sweet of it when it come to ethanol fuel. It's not cost effective.

What are you using?

Schaeffers Moly EP Oil Treatment.

Thanks, will give it a try. Restore is one that I have used with good success also, unfortunately nobody here carries it anymore for some reason.

 

[powerstroke cowboy]

I have never used that stuff before. But I have seen it on the shelf.

The moly is thick and slick.

Finally, an area filling station that offers ethanol free 87 octane as well as 91 with individual nozzles. Not thrilled about the prices, though.

 

[pbillyi69]

our price for gas is about 4 or more and the efree is 550 or more

Ouch, the prices here have increased 40 cents per gallon in the past several days. Although #2 diesel fuel is now less expensive than gasoline like it was back in the day!

i saw a sign for diesel at 5.05 today

 

[Joe Kidd]

E87 $3.09
Non E89 $3.99

 

[Greg Newman]

Today diesel dropped below 87 octane.

 

[FergusonTO35]

Diesel hasn't been less than 3.99 here for years

 

[huskihl]

Diesel is $4.34 here

 

[thedude74]

Both gas (87) and diesel are $3.79 here. Last year diesel was $5.50.

I can't tell you what I've been paying for gasoline lately because I stopped looking at prices and just go where it's most convenient but I can tell you 16oz cans of coke went from 2 for $2.00 a few years ago to 2 for $3.00 recently and I'm not happy about it.

Dude, you gotta start getting your drinks at the fountain. Way cheaper and tastes better!
