Mid Grade gas makes noticeable difference on my Ranger

[Lefty]

I run synthetic in everything, including my power equipment. I’ve never noticed a measurable difference in fuel usage or power but I do know for a fact that the insides of the engine are cleaner.

When I still had Honda CR-Vs, every so many miles you had to do a valve lash adjustment to prevent burnt valves. When I had only one vehicle and less expenses, I ran Amsoil. The engine looked brand new inside. With the cheaper synthetics, it wasn’t as clean but was a heck of a lot cleaner than when it was fed dino oil.

So, if for nothing else, I’m a big believer in synthetics for that. So much so, I use synthetic oils in my differentials as well. Supposedly Mercon V is synthetic. I imagine Mercon LV and ULV would be.

I also just found out the 2019 requires a special Dot 4 LV brake fluid. That is listed as synthetic. As hard as that stuff is to find and as expensive as it is, the 2011 isn’t going to get it. Dot 3 works just fine.

Good to know that I am not alone. I will never forget the first time I did this. The car did not have a computer, but the tachometer showed that the engine ran about 100 RPM faster.

Chances are the previous owner of my Ranger did not use all synthetic. So I've put about 5 oz of Seafoam into the crankcase then driven it for about 100 miles before the next 2 oil changes hoping to dissolve some of the carbon deposits.

I saw DOT3 synthetic. I was confused.

My tach is stuck hovering around 3k regardless of engine rpms...She runs fine though, so Ima fix it later

That doesn't make any sense.

 

[Lefty]

That doesn't make any sense.

I filled up today, this time with upgraded gas. Sure enough, the engine ran noticeably better. Thanks!

Less friction. Motor runs faster.

Less friction. Motor runs faster.

Less friction I understand. More efficiency I understand.

But RPM is controlled - either by idle air speed controller or gearing. Nothing about octane should case it to increase.

Perhaps we're talking about a carbureted vehicle?

"The car did not have a computer,"

Then its not really a car is it, its an ar no c for computer

"ar no c"...
Does not compute...

Correct

Exactly

And the "L" is silent; like in "fish".

Named one of our dogs Wmack, silent W so pronounced Mack

Made my daughter and wife crazy, son thought it was great
The dog liked it too

 

[RobbieD]

Wow; your dog could spell? That's amazing.

But then again, I had heard of spelling bees before.



Alas; yet another thread going off the rails.
