Not sure this is any help, but Eric Lee of Lee’s Autoworks in Oshawa (a PCA/UCR approved DE inspection center) has two similar projects on the go (a 68 912 and a 69 911 I think but certainly from that era). He is doing the work himself so it may be useful to discuss the project with him?
So my first time in a long time visiting an Esso station — the extra 20 minutes of running time with only 4 groups at the DE weekend meant I went through a whole tank and was running on fumes as I left Mosport so I was forced into the first station south on 115.
Some observations — they are the only station I have been at that has 93 Octane gasoline (the recommended octane my car and I think all recent Porsches?) and all indications at the pump point to the fact that any octane gas that they sell could contain ethanol. I see no indication on their website that any of their fuels are ethanol free.
The requirements for ethanol content in gasoline I believe are provincially based. In Ontario retailers have to average 5% content across all brands sold. That is why they use the signage “May contain up to 10% ethanol” – so they can jig the percentage at will to meet their audit requirements.
My understanding is that the required overall percentage was due to rise to 10% this year and to 15% by 2025 — not sure if that is actually legislated yet so the whole landscape of what is available at the pump could change.
Just checked the Shell website and you are correct they state 0% ethanol. Maybe this is recent and I haven’t visited a Shell station in a while? The Ultramar and Costco have always been traditionally less expensive for me (Costco usually 5-10c per litre) so my habit is to buy there.
I haven’t read the article — no magazine yet here.
Costco Premium and Ultramar Premium are both ethanol free(Costco everywhere I think– Ultramar certainly where I am). Shell Premium I am not so sure is ethanol free everywhere (at least where I am the pumps don’t indicate it so) so that may be station dependent.
The problem with Ontario is that it is a requirement that gas stations average 5% over all retail sales so you never really know what percentage ethanol (or even if there is any) ethanol when the pump is labelled “may contain 10% ethanol). My understanding is that newer Porsches are OK with ethanol but older (not sure where the cutoff is -1996 and water cooled?) cars Porsche has indicated should not use gasoline with ethanol.
My water pump snapped off (2006 Boxster owned since 2014 and 90000km) on Hwy 115 half way through a CTMP track weekend at about 145000 km. There was warning though — seepage around the pump. The irony was that I had a new pump scheduled to be installed the following week.
Another common failure is the AOS (I had mine fail filling the air with oil smoke at 141000 km). There was warning there as well (a little too much smoke on start up) — should have heeded and replaced the AOS – the part is relatively inexpensive for a Porsche part.
I have also had a manifold header develop a crack in an inaccessible place (it was cut, repaired and rewelded at the cut at about 95000km and failed again at 150000km – so I had a used pair installed). I don’t think that is a common problem though.
I just this weekend had a gas tank vent line/solenoid replaced that was causing an intermittent CEL but again I don’t think that is a common failure.
Besides those failures everything else I have spent money on was discretionary (new wheels, upgrade stereo) and regular consumables -light bulbs, tires, brake pads, rotors and sensors and regular fluid changes (brake fluid every spring, oil every fall). I go through tires, brakes fairly often (I have been on track 6 times a year for the last 4 or 5 years).
Mine is on the hoist 6 times a year for track inspection so it gets a pretty thorough going over often.
Originally I was looking for a track guide like the ones included for Mosport GP, Shannonville and Calabogie before I drove the track. But that need has passed after I drove the track at the Friday event last DE weekend.
You get one event allowed without needing an installed fire extinguisher and I think you can rent a helmet from Braidan at the track if you prearrange it. I also would encourage you to sign up for another event (other than the IDS).
