Slightly thicker oil for a high mileage 951 ?

[ukmastiff]

Moved to oil section by me b4 a mod does

 

[944 man]

Oil section? If its 944 related then it belongs in here, in my opinion.

 

[ukmastiff]

Sorry , I tend to hang out here as it seems to be ' the best' eheheh but I know mods can be a bit fussy re posts in wrong sections so I moved it. I would appreciate any opinions especially in the 944 section of course []

 

[edh]

give us a bit of a clue - thicker than what? []

What's your oil usage like? - all the turbos use a bit, particulalry when driven hard.

If you want a synth - Silkolene 15w50 is good, mineral i would try maybe Valvoline VR1 20w50

Thanks for the reply ,

I think he meant thicker than the norm so to speek , and just wanted to know if anyone else had taken that sort of step . As per my oil section post i dont actually have any way of knowing what oil is in the car. I have only had the car 2 weeks so havnt got any real oil usage measure to give you im afraid. I dont think i've ever had car that actually used a real ammount of oil TBH as this is my 1st 'classic' so didnt realise to give you that info sorry.

If it helps , I dont think she's burning any real great ammount and she runs beautifully but she has a very minor oil leak which is soon to be fixed and that burns on the manifold it doent even mark the floor. If I need to measure my oil use over time to give you guys the best info to go on I will of course ?.

While I'm here save an extra post , what type of oil filter wrench do folk recommend is the cup type ok , it looks a bit tight round the oil filter to get one of those strap type things in and yes im an oil change newbie .

Cheers Mas

My High mileage 951 has 3 minor leaks, one of which burns on the manifold as the car warms up (with a lovely puff of smoke from under the bonnet at the first junction you stop at....don't be alarmed dear!)

I run mine on the lower grade Shell Helix which is 10w40 as I recall

You may want to look at some High Mileage oils, but I'm not convinced that they are anything more than good marketing at work. If your engines not leaking oil (after you get it fixed) and its not consuming an excess amount why would you change to a higher grade anyway?

There have been many discussions on this forum regarding oil and you will find opinions vary.

The only thing that matters about oil is it's grade. A 15w50 is the same a a 15w50 'high mileage' oil. It is marketting hype, just like semi-synthetic.

Unless you use your car for any purpose other than 'normal' use, e.g. if you track the car alot or race it, using it in extreme temperatures etc. then you should use the oil grade recommended by Porsche. If you use the Porsche recommended grade of oil and you are having problems like excessive oil consumption or struggling to get pressure then that is indicative of some other potential issue or problem with your car and using thicker and thicker oils will just mask the problem. One of the problems of using an oil which is too thick is that the flow of oil over the moving parts are the engine is reduced thereby reducing the cooling capacity of the oil, and oil is there just as much to cool as it is to lubricate.

Well you have to ask , I seem to be getting a 'minor' hammering for this question hehehe
It looks like a good quality 10w40 is the order of the day. Probably going to a seriously expensive one might be a bit silly on my car but defo not a cheepo one either.

I found it all Interesting anyway and thanks for all the input. Now I just have to get up the bottle to do my first ever car engine change might sound silly to you lot but even though im an ex electronics engineer and hands on in 'that way' I have never done an oil change in my life. Have to buy oil pan and filter wrench I think.

I agree with Scott on oil it seems.

There is a common misconception regarding oil, that good oil is expensive, this is not true. If a top-notch quality oil, like a proper ester based synthetic oil is £15 (per 5l) more than the usual synth does that make it expensive? I bet you don't even think twice about putting another £15 worth of petrol in the tank, why should it be any different with oil? At least with oil its only once a year or so, seems hardly expensive to me for far superior performance.

Some would say its better to change the oil regularly with a good quality semi than to leave long times between changes with a better oil, and I would agree, but I think its even better to change regularly with a really good quality oil and have some decent insurance for the long term longevity of your engine.

[944 man]

Edd, I honestly doubt that you can get an honest PAO ester synthetic oil for £15. All oils labled 'synthetic' arent synthetic, unfortunately.

 

[944 man]

I see now: sorry.

 

[ukmastiff]

Guys can some1 advise re the practical bits , is the sump plug accessible without raising the car and which oil filter removal tool will work ok in that cramped space is a cap type one ok etc Also my mechanical work mate says I 'must' buy oneof these oil tray with a lid type things to help re neat disposal , any opinions on that I.E do you all use one.

** I promise I will do what im told re the 'type ' of oil you win you win *** []

Unless you're of a very small frame you'll need to raise the front to get at the drain plug. The drain plug is behind a removeable inspection flap on the undertray but most of those flaps were lost or never refitted.

I removed my S2 filter with a standard chain wrench but a cup one would be easier. Because the filter is upside down it's hard not to spill a bit of oil so a tarp on the floor is a good idea.

 

[edh]

Definitely raise the front - I'd also remove the small metal undertray that fits round the sump (if it's still fitted) - gives you much more room to work. I collect the oil in a bucket. The oil shoots out at quite a pace & can go everywhere.

Leave the oil to drain for a while - it's suprising how much keeps coming out after you think it's all done.

The filter is best removed with something like this:
http://www.amazon.com/Worlds-Best-Universal-Filter-Wrench/dp/B000M96RVA
As it's upside down, you will drop oil down the side of your engine - some people stuff a load of rags round it to try & catch everything.

If you're feeling brave you could also drain the oil from the cooler - you need to remove the "batwing" to get at the cooler, and the connections are very tight, so I'd suggest that's left for now. You'll still have a small aount of old oil in the cooler, which will start to mix as soon as you start up the engine again.

I agree with scot my turbo has 140k on the clock and I have used the recommended oil grade without any problems whatsoever. The car is my daily driver and I don't track it so what would be the point in spending a fortune??? mine used to use about 1/2 liter every 2 - 3 weeks. occupational hazard of old turbo cars I am afraid. Sinec I have fitted a fully reconned turbo it has not required atop up yet. Not suggesting you go to those lengths but mine needed doing. There is a filter tool with three legs that fits on a 3/8 ratchet and clamps on to the filter as you turn the ratchet. just the job for my filter. It also helps if work provide with a pre-dirtied workshop to do the job in!!! i would also recommend dropping the lot and changing filter at least every six months depending on your usage.

Whatever happened to just hammering a big screwdriver through the oil filter and using it as a Tommy bar like wot we did as kids?[]

I tried 'briefly' to use a strap type wrench which I use for work, thought about a chain wrench but picked up a screwdriver and hammer too!
