Gasoline/Octane for Expedition/F-150

[IMm29]

According to the owner's manual, an octane rating of 89 is recommended for the Triton V8 engines. Also, according to a Service Advisor from Ford Alabang when i brought my ride there last week for a KMCU, 89 is the recommended rating. Funny, last few times I had it serviced, they didn't say having high octane fuel was bad.

Questions:
1. What gas stations in and around the Metro still carry 89 octane?
2. For Exped/F150 owners, what gas and octane rating do you use?

High octane isn't bad. Basically they were saying your ride would be happy with 89 octane gasoline, but something better won't hurt. That also means using high-octane won't give much improvement either, because it only needs 89.

splerdu,
ok, thought so. i was just a little bothered by what the SA said coz he said Vortex Silver (93) is too high and that i should go look for something with just 89 octane. so i went around and the lowest i found was 93.

thanks bro!

Vortex Silver ang gamit ng bossing ko sa Expe nila...no engine problem hanggang ngayon...

Running a higher octane than what is required will not hurt your engine. In some cases, it may slightly improve performance if the ECU/PCM allows some timing advance.

The octane rating published in the owner's manual of U.S. vehicles is "Pump Octane" and not the Research Octane Number (RON) that seems to have become a standard in the Philippines.

Philippine oil companies quote Research Octane Numbers (RON) to advertise their gasoline. U.S. pump octane is the average of RON and Motor Octane Number (MON). If you've noticed Blaze, Velocity and Caltex Gold are being advertised to have octane numbers of over 95 while common U.S. premium is only 91-93. Do we really get higher octane gas in the Philippines? No, we do not!!! Philippine oil companies just use the rating that gives higher numbers without informing the public.

To verify my statements, call the Technical department of Shell, Caltex or Petron and ask for the octane standard they are using-- RON, MON or pump octane.

i guess wala namang 89 octane dito sa local market today eh..the best thing to do is to use the lowest available unleaded gas na lang. wala namang harm in using a 93 octane eh. the purpose of high octane gas is to eliminate engine knocks lang naman and nothing else.

89 octane is an average of MON and RON ratings as used in the US as johnqpublic said. we use the higher RON rating here.

89 octane in the US is about equivalent to 95 octane here...

ah i see. coz my complaint with the exped is it used to gag when i rev it after a cold start. the SA said it could be coz of the high octane rating. anyway, after the change oil/tune up and battery change, without a change in fuel octane rating, the gag was gone after the cold start, so i would think it wasn't caused by the fuel.

i use caltex silver and shell unleaded since 99 and my lariat works fine no probs

i-share ko lang itong post ko noon sa isang forum:

The result obtained from the mild driving condtions is referred to as Research Octane Number (RON) and the results obtained from severe driving conditions is referred to as Motor Octane Number (MON). Typically, the MON result is lower than the RON result. Some gasolines show little difference between the two values while others can show adifference of greater that 10 octane numbers. The difference between the two ratings is called the sensitivity of fuel. If there is a large difference betwwen the two values, it means that the fuel may perform significantly better under mild driving conditions than severe driving conditions (assuming RON is greater than MON). It does not necessarily mean that the fuel is unsuitable for severe driving conditions, as the upper octane number (RON) may be significantly higher than necessary for good operation and so the MON may fall into a suitable range.

There is no worldwide standard for reporting octane number. Typically ocatane number is either reported as RON only or as the average result of RON and MON, that is (RON + MON)/2.

Tama si johnqpublic318. Dito we use RON. IMHO as long as ayos takbo ng makina mo sa fuel na ginagamit mo, better stick with that brand or fuel with a particular octane rating.

If you need higher octane, get toluene =)

[IMm29]

thanks. vortex silver is doing pretty well. :mrgreen: must've been some other internal problem.

[johnqpublic318]

Yes...

Mixtures with 92 pump-octane Octane Premium
10%...........94.2 Octane (pump... maybe around 99 RON)
20%...........96.4 Octane
30%...........98.6 Octane

Try to locate industrial chemical suppliers in the yellow pages. Some should be able to sell you toluene in 200-liter drums. A few years ago, I was quoted 5,000 pesos for this size-- not too bad. Mixing your own home-brew may be cheaper than off-the shelf additives.

Disclaimer-- Though it shouldn't be a problem, I have to say this: I am not responsible for your safety nor effects to your engine.

How toluene work toincrease octane rating? All the while i thought we can only use that for crude oi treatment. thanks to you guys. I really needs some advice because I just bought a ford lynx gsi. I drove it before settling and the engine is really amazing so I decided to get it instead of my other options. However, after paying it the seller told me to use only petron blaze and dont use lower octane gas not even vortex gold or petron xcs. Heck, to get that blaze thing is very difficult for me because inavailability on some petron stations near my place. I tried the xcs but pinging occurs on my engine and the sounds really change. is it normal katsikoters? do i really need to get that blaze thing for my car? I dont want to sell it because the performance really amaze me but considering his gas is really something to think about. I need some advice lads. Cheers
