best fuel option

u2

with the continuous increase of fuel prices, which brand and type do you think is best to use? consider prices and octane ratings pls

i'd also like to know which one is best for a 97 mitsubishi space wagon. currently, i'm using shell velocity but find it way too impractical already. hopefully, others may give inputs on this.

thanks

If your car's stock (no modifications) and you use it as a daily driver in the city anyway, just get the fuel with the octane rating recommended on your car's manual.

Strictly speaking, you don't need high octane and there's no real benefit to using it in a stock car---not even the "added power" selling proposition oil companies want us to believe.

93 octane is good enough for most cars made in the 1990s...the one I fill up most often is Caltex Velocity Silver.

thanks shun_sakurai, some of my friends recommend caltex silver too (were you referring to vortex?). no real modifications to my space wagon except for 17" wheels (will this be a problem?)

also, will there be an issue if i suddenly change fuel type? some people say that it's ok to mix, others recommend totally draining the tank first. what do you think?

thanks again.

other inputs also welcome.

The issue of "added" power" comes in when your car needs premium gas (generic term for velocity, infinity, xcs, gold & the higher end petron blaze). Almost all cars in the country doesnt need it. Most often than not the act of putting premium fuel acts a placebo.

I wouldnt be too worried with mixing unleaded with premium or different brands of gasoline. You should only worry when you put in diesel or kerosene.

As previously state you only need high octane or premium fuel if you have high performance vehicle or a vehicle that has a modification in the engine.

There are other ways to save on gas like removing unneeded cargo in the car, driving calmly and planning out your trips. Keeping your vehicle maintained is a big thing too. If you can walk it you're better of doing so. You dont spend on fuel and you burn off a few calories.

Using tint that actually blocks out heat from the sun helps. Those "manyak" tints may filter out visible light but other parts of the light spectrum that contribute to heat may still come in if your tint isnt designed filter them out.

As long as your on the stock timing settings and use the recommended heat range spark plugs (stock spark plugs), regular 93 octane should be OK.

We usually gas up on Petron XCS though (95 octane) as our cars seem to run better with it and we get slightly better mileage with as well (no actual data though but its gauged against how much P500 lasts in our daily drives :P).

Hahaha nagkamali na naman ako!

Vortex Silver nga gamit namin...wala lang, nakasanayan lang. Thanks for correcting me hehehe

Bigger alloys usually mean more rolling resistance to overcome, so that might dent your fuel economy a bit. But in terms of octane requirements, no diffrerence

I don't see any difference using different brands of fuel. Adjust your driving style if you want to save fuel.
