Premium...?

[The_Hawk]

That's exactly what I'm doing. I suspected that might be the case. I put in $20 of premium 95 and did 100k's with it (I do a lot of peak hour driving) and I put in $20 of premium 98 last night. See how it goes.

How did you go with your tests?

A better test would be to run to empty then fill up with one, run a full tank, then fill up with the other. You will get a much more noticeable difference over a tank. If you don't, well there is your answer. $20 is only about 15l or so you may not notice a difference, even if there is one.

(well technically it would be best to run a few tanks of one, then a few tanks of the other and average them, but lets not nit pick).

98 Premium seemed to get a bit further and the car seemed to run a bit smoother. BUT in regards to it running smoother, this could be a placebo. And $20 did an extra 40ks with 98 instead of 95 but I did different driving so that could also be put down to that.

Last time I tested premium over regular I came to the conclusion that YES I did get better economy, but it cost me more. End result was that in $/100km terms I was about the same, maybe a little better. This is increased with more freeway driving and decreased with more city driving.

In terms of looking after the engine, premium is better for it since it burns hotter and cleaner that regular keeping the engine cleaner.

In short, run Premium, you car will like it.

G'day chaps,

was wondering if anybody knows what ever happened to unleaded 95 at Caltex petrol stations around Sydney. I purchased it there several times at the beginning of the year but now have to fill up with the more expensive Vortex. Took me a while to realise ...

Cheers,

We ALWAYS use Premium (95) in the T4 Transporter and the Golf CL (1.8L single point injection). We did an experiment with Shell 98 but found no added benifit around town. I believe it will be better on a l o n g run.

When we bought a Mk 3 Golf new in 95, I used 2 tanks of 91 RON, 1 tank was the worst fuel economy I got with the car in 2 years of ownership.

(5 & 98 RON have more detergents in the fuel to help keep the injectors clean (much cheaper than injector cleaner), fuel also burns at a higher temperature keeping the inside of the cylinders cleaner.

I hope this helps.

I've always used premium unleaded for all my cars since the big ol' Calais of 1996. How does the ethanol affect the FSI engines, though. Save the environment okay, but I'm not swapping my GTI for a Toyota Prius, because Al Gore can't get over losing the elction against Dubya Bush! Maybe a Honda Civic Hybrid, but I love my GTI and that's the moral to my question.

I always use 98+ octane petrol.

Can't say I realise the savings, because the darn foot stays down just a tad longer just after filling up.......

i have always used BP 98 Ultimate i all my cars (all of them had a 95 octane minimum requirement) and i love it. You can notice the difference, im not after saving $2 a week if it hurts the engine
