#4719424 - 04/07/18 12:10 PM Trying Shell V-Power

I started scanning the 200+ posts on this fuel and additives topic looking for some answers to my questions but gave up. So at the risk of opening up a well beaten subject here goes:

I will be running Shell V-Power in my 95 Mercury 4.6 2V for the next while. The questions I hope to answer are:

1. Will gas mileage improve (even slightly) because the car's engine control computer will make adjustments for the higher octane 91 (was running 87) ? The thinking here is that more volatility equals less volume of fuel required. Does the computer have this capability or does it just adjust only when it gets a knock signal ?

2. My go to gas was Pioneer which is not on the "Top Tier" list whereas Shell is. Shell and all Top Tier fuels, have more detergents which should help clean injectors, intake valves, comb. chambers, spark plugs, etc. Should I expect easier starts, smoother idle, better acceleration and the like ?

3. Probably the most compelling reason to try a 91 octane fuel is to eliminate ethanol use for my (older) car in particular. Much has been written on the pros and cons of ethanol and I am in the cons camp, mostly because of it's negative effects on fuel systems and engines. This is not really a question that can be readily answered by trial and observation. However, my research indicates that ethanol was introduced as a fuel supplement around 95/96. So my 95 car was not designed to use it. I don't know what design changes were made for E85 cars, so I don't know if ethanol is doing harm to my non-E85 vehicle. I guess that is kind of a question.

Try it out. My old Explorer showed no benefit for my buying 93 as opposed to 87 at Costco. But my 2016 Edge 2.0 comes alive on 93 octane. Some vehicles seem to benefit while others don't.

I would say yes but for none of the reasons you state.

I believe shell has a ucl in their additive which will give you the differences indicated but mainly the smoothness is noticeable .

One of my cars is sensitive and I can tell the differences in fuels. where shell is slightly smoother than others.

I notice the similar smoothness when using a maintenance dose of si1 for a tank or even the second diluted tank so it is not something special to shell, its just ucl.

Ultimately be a scientist and just try it for a few tanks. Write down your hypothesis and how you intend to evaluate.

As far as fuel economy, it may technically also improve but at such a small value that it won't be measurable. like 1% or less (assuming only vpower change not ethanol %)

I use it in my Briggs Sears mower, STIHL chainsaw and my Shindaiwa string trimmer. Works great and I have no start issues with it.

If your 91 is ethanol free, you'll see better mpg due to the pure gas. I highly doubt the computer in your '95 4.6 will advance timing to take advantage of the higher octane fuel though.

European octane ratings are calculated slightly differently. Yielding a higher number. I can get 93 here or Sunoco 100 racing gas.

Euro 98 (RON) is equivalent to 93 here (RON + MON/2).

Yes it is =), so you get 93 V-Power then in US?

Thanks for the responses. We can get 93 octane here from Petro Canada for one, possibly others.

Yes, the Eastern US usually has 93 for high test. Out West they usually have 91 or 92 as standard high test.

Maybe where you are!

10% ethanol blended gasoline has been available in Iowa/Nebraska since the late 1970's.

No..... I often add 5-7 gallons of E-85 to my 1996 Mustang GT 4.6 to stop pinging.
It runs the same... just gets much worse MPG when I do.

EXACTLY!!!

The 99 Camry had worse fuel economy. About 2 mpg less. I only did it to lock myself into Shell's Gold fuel reward status. I want to see if the 14 would have any increase with the 10.4:1 compression and Dual VVT.

I tried both 87 and 93 and didn't notice any difference in power or economy only thing i really noticed is weight reduction of my wallet. Shell gas in my state is lack luster anyway and can contain up to 20% ethanol on the regular pump.
