Premium fuel?

I do not buy valero if i can keep from it. And out of principal steer clear of Exxon. Exxon is only because of oil field experience.

 

Wind was 5-10 mph out of north for the duration of the trip. Temperature was max of 20 degree difference from south texas through oklahoma. Once i got to missouri temperature dropped more. Then i was looking at 40 degree difference from south texas to northern missouri.

 

Is this a trip you anticipate doing a lot more? More data would help.

 

No max of once a year. I try to keep the mileage low on my truck. Currently i get between 8 and 15 mpg but that is the tires and my driving. Majority of driving is responding to emergency tones.

 

Tail wind.

 

I was traveling from texas to missouri and wind was out of north. How was there a tail wind?

 

Stick with 87 octane like it says in the owners manual... and name brands like shell or chevron for the additives/detergents to help the engine in the long run.
Using premium might increase your MPG but barely enough to notice and not worth the extra dollar.
As for performance I'm not sure but I hear e85 gas actually increases performance enough to notice.

 

You mean 5 to 10 miles per Tank?

 

No i mean per gallon.

 

The Owners Manual says 87 or Higher Top Tier Fuel.

 

My point still stands... never said it didn't say using a higher tier wasn't aloud.

 

Top Tier fuels have nothing to do with Octane Rating.

 

Okay.

 

Good deal, just wanted to make sure we were on the same page. I was agreeing with you when you said stick to the Manual. It does say use Top Tier 87 or higher.

 

Correct, but 87 or higher top tier fuel means 87 octane or higher, but to use top tier fuel because of detergents.

 

Exactly what l said, could not agree more.

 

Yep that's why I also mentioned sticking with name brand gas such as shell or chevron, they have top tier gas.

 

Ethanol free FTW

 

Valero is the only Top Tier station l have access to in my area.

 

If you can find it.
