Orion03 Posted 18August, 2014 Report Share Posted 18August, 2014 So Porsche Melb wants me to service my car yearly and not every 2 years as the manual says. Now I was going to do it yearly anyway but I was interested in what they would say, so I asked and got this reply: Hello, Thank you for the email. With regard to service on the Porsche, Australia is a "B Grade" fuel market and as such, it is necessary to service your Porsche every year or 15,000 km's. Whichever occurs first. If your manual states every two years I would suggest that it may be possible that the incorrect service book is in the vehicle. In Europe and North America the service interval is every 2 years. Was your vehicle originally sold in the U.K? So.... Aus is a B Grade Fuel market?? Link to comment Share on other sites More sharing options...
StevepGT3 Posted 18August, 2014 Report Share Posted 18August, 2014 Australia is an A grade RIPOFF market Link to comment Share on other sites More sharing options...
sleazius Posted 18August, 2014 Report Share Posted 18August, 2014 Probably referring to the Sulphur content of Australian petrol. Whether this actually means you need to service more often I simply don't know. Japan / EU = Low Sulphur US / AU = High Sulphur Link to comment Share on other sites More sharing options...
Orion03 Posted 18August, 2014 Author Report Share Posted 18August, 2014 But note he says US is 2 year service. Link to comment Share on other sites More sharing options...
Russ Posted 18August, 2014 Report Share Posted 18August, 2014 did he mention what difference it made? are they changing fuel filters and seals every 15,000kms? Link to comment Share on other sites More sharing options...
Harvs11 Posted 18August, 2014 Report Share Posted 18August, 2014 Not scientific evidence, my buttometer shows that the tank of 100 octane fuel I got at United in San Remo is definitely NOT A-grade. Link to comment Share on other sites More sharing options...
Orion03 Posted 18August, 2014 Author Report Share Posted 18August, 2014 If he had said that they recommend changing the oil more frequently so that the IMS bearing doesn't explode then I'll agree with him immediately! :-) Link to comment Share on other sites More sharing options...
SteveT Posted 18August, 2014 Report Share Posted 18August, 2014 Maybe it's got a bit more to do with the general pricing policy of Porsche Australia than fuel quality Link to comment Share on other sites More sharing options...

ArthurK Posted 18August, 2014 Report Share Posted 18August, 2014 I could understand changing your oil yearly but to blame it on the fuel is stupid. The fact we have poor fuel at the pump has more to do with the crap that ends up in the fuel at the servos more than anything else. The number of times I have had water in a tank of fuel by filling up at a Shell servo is nuts. Link to comment Share on other sites More sharing options...

I can actually show you graphs in boost curves how bad the car drove. drained it and put BP back in. drove like a dream again. Link to comment Share on other sites More sharing options...

clutch-monkey Posted 18August, 2014 Report Share Posted 18August, 2014 when i got my motorbike license the dealer warned us not to use shell premium in their triumphs as it made them run terrible. never understood it myself as it all comes out of the same refinery?

hugh Posted 18August, 2014 Report Share Posted 18August, 2014 My HSV runs pretty bad on Shell and Caltex but like a dream on BP. As the wise overlord of this forum once told me - BP stands for 'Best Petrol'. Agree with comments above, smells good to me. Link to comment Share on other sites More sharing options...
tazzieman Posted 18August, 2014 Report Share Posted 18August, 2014 Never had a problem with any fuel down here. Maybe in 35 years I've just been lucky Then again I don't own highly strung cars Link to comment Share on other sites More sharing options...
firstone Posted 18August, 2014 Report Share Posted 18August, 2014 Caltex and BP are both great up here. As to the dealers comments...fooee Link to comment Share on other sites More sharing options...
StevepGT3 Posted 18August, 2014 Report Share Posted 18August, 2014 I haven`t given the newer shell the chance to ruin my day, but the original v power or v max or whatever it was called, if left in the fuel rails too long would evaporate into a jelly that required total dismantling and cleaning of injectors, rails and even fuel lines,lots of swear words and many hours were spent vowing never to darken their forecourt again.

Simonk Posted 18August, 2014 Report Share Posted 18August, 2014 Can someone tell me how cars went from the traditional 6 month / 10,000km service interval to 2 years / 15,000km intervals? Holden/HSV added a bigger sump to their LS2 and that was enough to lengthen the service interval. So more oil means it degrades slower? I can't help but think that it's all marketing that could potentially shorten the lives of engines in the long run. That wouldn't have any effect on the manufacturer as it would be way out of warranty by then. If PC used that font in their response to you, then I'd automatically assume their response was full of shit! Link to comment Share on other sites More sharing options...

T-Man Posted 18August, 2014 Report Share Posted 18August, 2014 Hmmmmmmm. I generlly use Shell followed by BP. I can honestly state that I have NOT had any bad experiences with either. I reckon 25K is way too long between oil changes anyway. That is of course if that's what Porsche intend to do on the shorter service. Link to comment Share on other sites More sharing options...

You should try BP next time you feel up, might notice a difference? or you've been lucky haha. Link to comment Share on other sites More sharing options...
Orion03 Posted 18August, 2014 Author Report Share Posted 18August, 2014 You guys make me want to try BP. And the use of Font was mine. Link to comment Share on other sites More sharing options...
T-Man Posted 18August, 2014 Report Share Posted 18August, 2014 You should try BP next time you feel up, might notice a difference? or you've been lucky haha. I'll certainly do that Pauly. Get a big dose of BP before the next run and try pay close attention to the way the car runs. Link to comment Share on other sites More sharing options...
Pauly Posted 18August, 2014 Report Share Posted 18August, 2014 Here are my logs: First one is with BP ultimate (98) Second one is with Shell Vpower (98) - at 4k rpm you can see a flat spot where it suppose to be at a ~345 and increase to ~355 at 4250rpm but has dropped and stayed at ~320 and stayed there until 4250 rpm. ****Note the red and blue lines have changed sides between logs**** Link to comment Share on other sites More sharing options...

That wouldn't have any effect on the manufacturer as it would be way out of warranty by then. Build tolerances, materials and lubricants have improved over the years. Better engineering means engines run cleaner and with less wear. So service intervals get longer. Well that's the theory anyway. Link to comment Share on other sites More sharing options...
