I whacked some 98 octane in ole red yesterday and then went for a drive thru the vineyards and back via west lake macquarie. Longest drive in one go since I bought the ole thing and it went great. ABout 140klms and didn't miss a beat.

I noticed that it was flyin along the roads like never before. I was catching cars in front of me.....

I hadn't driven it on major roads or roads over 70 kph since putting my engine back in so I was surpirsed to say the least.

Is it my imagination or does the better fuel pump the dubs with aparently more power?

I had just been running standard unleaded prior.

well there is a lot debate about fuel some say it will screw ya motor ,me i have used unleaded fuel for 8-9 years and had no bother, both in 1600 and 1800 and a blown 1600 so i say its ok and 98 should be even better.
mr. berg said that vw's from the early 60's can run unleaded , and as does it make better power why not me i use kero if i had to

Mine doesn't like the 91 octane but runs fine on the 95 octane.

we always use 95 in all our cars.
Bring ole red to the dyno day and we will test it out on the dyno

Hey red, saw ya car in at the Brewery the other day, are you still doing the walk thing on Sundays?

I run my VWs on BP Ultimate. One of my "work" situations requires we use it in all sorts of cars - Porsches, Lancer Evos, HSVs, FPVs, WRXs, Lambos etc for track work - and it is always good stuff. When tuning my 1916cc VW recently I could tell the difference almost straight away after I topped up the tank.. and that was in the shed, just setting the idle.

yep I like it!

A good flogging on freeways etc can really 'clean out' your engine if it has been choking around town for few months, too. When my VW was my daily driver, it always felt fast, willing and smooth on a Monday morning after I'd been to Canberra or somewhere for the weekend

All VW's were made to run on unleaded fuel from 1968 as unleaded fuels were available in the US in 1968 and that was the leading market for VW design and specifications.

98 Octane is the best for your car and it is advisable to buy your fuel from the same Petrol station and even the same bowser if at all possible. Never fill your car when the tanker is filling the tanks as this will stir any rubbish up and potentially into your car.

Cheers,

Go the 98 always. More power, better economy, cooler running, better engine life

But be careful when travelling as the 98 doesn't get used by a lot of people as its to expensive so it sits in the tanks for a long time. We had this problem when we all filled up at Tamworth last year on the way up to Warwick all 3 bugs fuel filters blocked. One bug did a fuel pump. So just be careful. We always put it in the bug at home as we always go to the same servo.

yeah good point Rose - I got stung when I bought PULP at a little creepy servo on the way to Coffs a few years ago - I limped into Sawtell on 2 and a bit cylinders and had to drain my tank and carbies in the caravan park! Always buy PULP at bigger, high turn-over petrol stations

Lots of people have differing opinions and experiences with high octane fuels.

Does it produce more hp? i have never dynoed my car with anything other than BP 98 unleaded so i can,t say. But i have found my car always runs and feels good after a event, ie good thrashing.
When i was installing my MSD ignition i did foul the spark plugs. Now i believe it was because i had the car idleing in the shed for long periods without a good rev to clear the plugs.
My dyno dude has many years experience with off road VW,s and dyno operation. He told me to stick with bp 98 because it will reduce the risk of pinging in high compression motors and different fuels have different viscositys, which may change or alter my jetting.
I reckon find a fuel your car is happy with and stick to it. whether it,s 98 octane ,95 or standard unleaded.

I always use 98 but dont have much choice as the engine is tuned for it. Slightly off topic but I am in Canada at the moment and wentr to fill up at Shell. Their version of V-Power (our 98) is only 91, thats the highest they sell from the pump. The other 2 choices ate 89 and 87. What the hell is going on here?

Hi Andrew

I think they measure their octane rating in MON over there, we measure it in RON

Approximate conversion between RON & MON

RON MON
90 83
92 85
95 87
96 88
98 90
100 91.5
105 95
110 99

Hey Donn yep have been going in just depends on how much the wifes feet hurt. She has stress fractures in both feet so some days better than others.
Rose the Dyno day would be good but I dunno about putting the ole thing out there running her little her engine off. Will see what happens. I was hapy with how it went though. Much more fun doing an arvo drive iin Red compared to the Monaro being all closed in.

Well bring the Monaro to the Dyno day. The dyno day is just for a fun day not serious & bbq get together.

Hey Rob, We always run the 67 on 98, little bit more expensive but we have to run the GTi on it anyway. Was good to see you guys the other day we will have to get together for a BBQ or something soon.

Hey Jodi. BBQ sounds gr8 but on one conditon....... you must wear something other than your jammies......lol
With the hot weather happening like it is give us a call and bring your swimmers. We may as well use the pool.

I use 98 (BP Ultimate wherever possible) in the 1800 (typeIV) Bay, usually, but I don't notice the difference if I use 95. My Splitty 1776 runs 91 or whatever, usually 95 these days.

I noticed that after I (almost?) lugged the Bay up a reasonably long hill in 4th at WOT (*) she drove like a champ all the way home, without the usual misfiring thing she has been doing for the last couple months. Then again, she is very temperamental, might have been coincidence.

Cheers, A.

* Yeah that's bad in general I know but that motor pulls great at 2000RPM, as it should with 140PSI across the board, but above 3000 it's all over. Flat cam? I don't know. So it is an extremely low-revving motor...
