Reported cause
(or any car) Mine has 54k on the clock and gets used every weekend problem is the millage/use is split across three cars so therefore is less on all.
Leading evidence: 'millage/use is split across three cars' (1 discussions report identifying this cause; no attributable repair resolution). Across 1 matching discussions, the most frequently mentioned possible cause is 'millage/use is split across three cars' (1 discussions; 1 report identifying it and 0 suggest it). The most frequently discussed action is 'Replace due' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

I guess if you are only doing 3K a year then oil would require changing due to lack of use, if you see what I mean.

We run a fleet of old mercs and use semi synthetic..we have a 300D with 470K miles on it...agree small price to pay guess its a bit load dependent so 6K change makes sense...nice problem to have three cars!

In fact my heads a mess with Fully synthetic oil I change my oil regular mainly because its the same cost as a tank of gas and could save me a bill of £££££.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Evening all, quick one re oil if anyone can help pls,
car C2 man, is about 6K miles from last service and looks like needs 0.5l oil...so Mobile 1, which one should I feed it, 0W 40 or 5W 40, or 10W 40??
Thx[

Hi guys, thanks, are you saying you change oil every 6K, including filter? Thought service schedule was up to 12K? Had never heard of Miller but had a quick look and seems decent enough Bst Andy
Hi Andy, For what it costs yes, I change my oil every year or 6k. Mine actually only does 3k-4k before I change the oil. I would never leave it till 12k. I don't think its cost effective.
Hi Thirteeneast, thanks for the comments, how many miles has your 996 done? Mine has 118K on the clock. I do about 12K a year so I could change oil twice a year at 6K. When you say cost effective are you refering to engine blow up then?? Would have thought modern synthetic oil would still be doing a good job at 12K, some modern service intervals go up to 18K?? I guess if you are only doing 3K a year then oil would require changing due to lack of use, if you see what I mean. Bst Andy
I don't think fully synthetic oils do a good job for consumers at all, If they did cylinder scoring on cars under 100k would not be such a common fault. In fact my heads a mess with Fully synthetic oil I change my oil regular mainly because its the same cost as a tank of gas and could save me a bill of £££££. It doesn't take long and is the single most important part of your car I don't let any of my cars do more than 6k before an oil change. Not even the banger I use for work it just makes no sense. If theres anything wrong your going to pick up on it 6k earlier. Just my choice of course but a small price to pay in grand scheme of running a Porsche. (or any car) Mine has 54k on the clock and gets used every weekend problem is the millage/use is split across three cars so therefore is less on all.
Possible that synthetic oils dont go a good job, I guess if you only used mineral oil scoring might appear earlier, or possibly later? We run a fleet of old mercs and use semi synthetic..we have a 300D with 470K miles on it...agree small price to pay guess its a bit load dependent so 6K change makes sense...nice problem to have three cars! Bst Andy
I wouldn't worry about bore scoring on a 3.4. It is pretty much unheard of. I would say use an approved 5W-40 synthetic, and change it every 6000 miles, and you won't go far wrong.
