engine oil??

[944 man]

The link wasnt intended to provoke viscosity discussion or disagreement. I thought that it might be of interest due to the discussion about group three and group four oils, who still uses them and how even if your oil is really a group IV type, whether being ACEA or API approved means that itll actually protect less in favour of a tiny improvement in emissions.

As I understand it, oil temperatures typically don't exceed 110degC on a spirited track day and usually stay down below 100degC. 150degC is a LONG way up for this, and if you are spending extra on oil because of this property then you are wasting your money.

I bet oil in some parts of the engine will see higher than 110degC.

Look up " Opie Oils " and ask the expert

Used by car forums for good advice for years - good prices on high performance and specialist oils too []

... a case in point; his advice is no doubt good and very technical-sounding, and he uses it to sell hugely over-specced oils to people who have no need for that degree of sophistication.


Oli.

I`m not sure where you got that information from.

He is known for offering impartial advice and have seen him recommend simpler oils to people on many an occasion. Usually I note that people look for over the odds oil when they dont need it.

Regardless if you want oil (of any type) his prices are very good and the web site offers quality oil at decent prices. (I have no personal interest other than as a purchaser)

Personally I use Fuchs Titan - not an overly high spec, decent price (and my choice [])

Oh yes....................110 is easily achieved and 120+ is common - a bit high but not disastrous - at that point I`d recommend supplementary cooling.

Simon at opie oils usually gets asked by people what oil to use in their cars, most people myself included dont want the bare minimum, they want something that will handle all you can throw it through the service interval. I often see Simon recommend the semi oils as suitable but also states better performance can be had from the fully synth oils, this is obviously true as most of us are driving performance cars and getting the most out of our driving, some are using them on the track too. There is nothing misleading or overselling going on imo. If you are driving a fiat panda to the shops and back your oil needs may be different....

Chaps,

That's my point - look at your requirements, look at the engine you are running the oil in, look at the service intervals you are running, and decide upon what you really need! If you are doing trackdays, you may (note: may) need higher-spec oil. If you are racing, you probably will need higher-spec oil. But don't be sucked into the "XYZ is better therefore I need it" trap. If you have money to waste (and yes, I mean that - waste) on things you don't need then don't let me get in the way of you spending it; better oil won't do your engine any harm, but it won't do it any good either, and I'd rather keep that excess cash to spend on fuel, beer or something more useful. (I'd also suggest that doing 120mph for hours on end on an autobahn is pretty easy for an oil; engine nice and warm at ideal operating temperature, lots of cooling air flowing through the radiator and oil cooler, 5th gear engaged so the engine is running at a little over 4000rpm, no major stresses - all well and good. Any engineer will tell you that the vast majority of engine wear occurs when an engine is first started from cold, when the oil is in the sump and thick and sluggish and the bearings are unprotected).

No matter what oil you choose there will always be a 'better' one. Don't fall for the sales hype in buying things you don't need. Simon at OpieOils is a knowledgeable chap, and the advice he gives on oil technology is good. But he makes his living from selling oil to the likes of you (not me). Best of luck to him, he clearly knows his stuff and I wish him all the best, but bear in mind that when the 944 was made the oils it was designed to run on would fail every single oil specification rating in place today - and yet Porsche still tested (and approved) 944 engines under the most harsh conditions they could cook up, and deemed them suitable for market.

You pays your money and you takes your choice. Who here has had an engine failure due to lubrication problems (as opposed to head gasket failure, wrong mixture, detonation, belt failure or something else)? Stick your hand up and put up a link to your thread about it. Anyone? I don't see many hands up guys .... and on that basis I'll carry on using cheap semi-synth oil in my 170,000 mile S2, just as I have done for the last 70,000 miles and still marvel at the fact that it doesn't use a drop of the stuff and produces more power than it did from the factory.

Lowtimer - good point about turbochargers; I appreciate that they are more demanding of oils and the requirements are higher than for N/A engines.
