Tremors and high octane fuel

[Dgc333]

Yeah ASE is outdated unfortunately.

Can't believe you would make such an uninformed comment. ASE has over 50 different certifications in all phases of automotive service and repair. Basically if you want a good paying job in the automotive repair & service industry you better have appropriate ASE certifications. Certainly being ASE certified does not guarantee that you are a top tech but it does ensure that you have an understanding of the basics and are enough on the ball to learn. Even Ford Performance thinks enough of ASE certification that they won't give you a warranty on their tune unless it is installed by an ASE certified tech.

My son has a big display in his shops waiting area of why you want an ASE tech working on your vehicle and he displays the certification of all the techs that work for him.

Granted modern computer controls have allowed engines to produce more power and be more efficient but the physics that governs how a 4 cycle internal combustion engines works has not changed.

It makes a difference when you run your numbers, when they switch to Winter Blend at your gas station in your part of the country (around Nov. here), I lose 1 mpg anyway.... and gain it back in the summer
My average driving habits are about the same city/hwy/towing every month so that is how I test
I reset Trip 2 every month and I have noticed between 19.4 and 22 between grades, I have gone 87, 89, 92 and then 92 Non-Eth yes I do see a 2 or 3 mpg dip like 1 mpg per grade, so if 1mpg dont bother you run the cheap stuff I dont like corn in my gas LOL averaging 4k miles a month it matters to me, when I got this truck a few months ago it had about 10k on it LOL now today it has 25k
this month was 92 w/Eth Premium I am averaging 20.2 I always get 21.5 with 92 non-eth and it just feels better too LOL right now at $4.39 for Non-eth it cost $5 more over a full tank, big deal, it probably matters if you are in a warmer part of the country, I am outside any city in Upstate N.Y with more hills than flat roads, its 30 miles round trip to Walfart or Wegmans
I have no Tunes no aftermarket engine Mods, and I have 285/75 tires

Please answer the question. How does YOUR mileage vary?

Mine didn’t vary to my knowledge but I never watched it too closely. I traded in for a v8 Silverado so now I do watch it more closely! Painful!

Although many folks here have discussed timing, programming, towing, driving style, air temperature, etc...a few have actually answered the original question of whether their mileage and performance increased with higher octane fuel. The answer appears to be neither improve significantly, and surely not enough to justify the added cost of premium gasoline.

If ASE certifications were that important then why is it that Ford does not require Dealership Service Technicians of any level to hold a single ASE certification? Would you believe that GM and whoever took over Chrysler Corp. Does not require ASE certifications for their Dealership Service Technicians either? If it was that important than it would be required. I myself have wrenches for over 10 years now in Automotive, Heavy Duty Mining and now Forklifts. Not once was the ASE Needed. All it has been is a simple "Shiny Blue Patch" that makes those who know nothing about cars go ?. All the Technicians I have dealt with that have ASE Certifications also don't know what they are doing when it comes to mechanics. At best they know how to change a part and even that is questionable.

So before you try to say that it is an amazing standard, vehicle manufacturers have to recognize it first.

I ran three tanks in a row of everything and logged the mileage. 89 was 1.5 mpg better than 87 so it doesn't cost any more to run that. Saw no difference with 93 over 89. I run E15 88 when I can since it costs the least (I drive a lot) and mpg is about the same as 89.

Politicians and their special interests groups need to get that shit out of our gasoline.

If you don't care that running 87 will make your trans blow up, your blower blend door stop working and water get into your spark plug holes, you do you... ?

There is no legal requirement to be certified but it is certainly encouraged by all the automotive manufactures. You will get ASE certification when you complete GMs specific training. All the auto manufacturers have brand specific training as they should which is certainly more important than a general knowledge ASE certification. But you can't underestimate the value of the blue logo. It's a differentiator when applying for a job. Shows your employer that you are committed to becoming better at your craft that can only help when review time rolls around. For the dealership it shows the customer a level of commitment to having talented and skilled technicians.

The Ford dealer where my two Mustangs and Ranger came from have the ASE logo on the wall in the service department waiting area. Just last week I had my wife's Jeep in for one of its free oil changes and they had an ASE display on one of the end tables in the waiting area with flyers on why ASE is important.

If you are committed to a career in automotive repair and service you are an idiot if you are not pursuing appropriate ASE certifications.

Just because the Dealership displays it doesn't mean the Technicians have it. How do I know? The second shop I worked at did just that.

You are the perfect example of what I stated before. The shiny blue logo simply makes you go "WOW".

Edit: to also prove my point one Nissan Technician I know that does have his A1 through A8 has told me the ASE test questions have been the same questions for the last 30 years that he has done them.

Many folks here have reported better mileage and better acceleration on their Ford Rangers when switching to higher octane fuel. I drive a Tremor and constantly monitor my mpg and reset it after going through a tank of gas. I just finished up a tank of 93 octane fuel, and was shocked that my mileage was exactly the same that I'd been getting with regular and I noticed zero increase in performance. Anyone else with a Tremor notice a difference between octane levels?

They all have the same engine regardless of trim level. The 2.3 ecobeast runs more efficiently with higher octane fuel. Driving style determines mileage.

That is the one thing many people fail to realize. A lot of this comes down to the fuel octane level highly affecting the available ignition timing. The higher the octane the More the ignition timing can be advanced without having to worry about ping or knock. The more you can do that generally speaking the more efficient it's going to run. As much as this does play into the fuel mileage by driving habits and conditions one might be him will affect the fuel mileage a lot more

I'm not denying that the 2.3 engine itself is the same. Whether one drives aggressively or mildly, the question is whether mileage improves with high octane. By saying that an engine is more efficient with high octane, do you mean that you personally get better mileage and performance with high octane?

 

[Dieseldean1]

Short answer- yes.

 

[NotBudule]

People go crazy and study every brand of oil that will go in their Ranger and then analyze it ad nauseum , but then turn around and put drip gas from a dirty can in its tank ...
