Driving style: Mostly motorway with occational country lane blast.
I was using Mobil 1 0W40 until I got the remap done and AmD did an oil change and put in Quantum Synta GOLD 5W40 as they said they thought the Mobil stuff was too thin. What do you think?
Thanks for the advice.

Hi, The 0w-40 will not be too thin, when hot both a 0w-40 and 5w-40 are the same viscosity, when cold the 0w is slightly thinner at very low temps then a 5w however these are still many times thicker to when the oil is hot, so it cant be too thin. According to my book you will need VW503.00 spec oil or a VW503.01 spec. CHeers Guy.

So there would be no problem topping it up with Mobil 1 then? I assume mixing VW503.01 spec oils is not an issue? Thanks again!

Mojo, I would suggest as a top option a 5w-40/10w-40 full synthetic for all year round use. The temptation when some engines have been modified is to use thicker oil, this is not always the case as you have a high rev limit, high revving engines do not like thick oil, and keeping around the SAE40 grade will help keep fuel dilution to a minimum. Hope this helps. Cheers Guy.

Hi, You have a choice, you can either go for a 10w-40 semi synthetic and change it very 5k or so, however if the car is going to get some hard use and Nurburg treatment then a full synthetic 10w-50 may be a good idea, it depends if you going to be keeping the car after the event. For the gearbox, yes you can use a full synthetic ATF, not many out there mind but we have the Amsoil ATF, the advantages of this are more shear/temp stable oil, basically peform better under hard use. Cheers Guy.

We recommend 5w-40 synthetic for this car. The most popular quality ones are Silkolene Pro S 5w-40 and Motul 300V 5w-40. Details of these and other quality 5w-40's can be found here: www.opieoils.co.uk Cheers Simon

Ok, Fuel dilution will kill any oil, its often caused by running rich, bad injectors, carbs and throttle bodies, that sort of thing. A top quality SAE40 (5w-40) will suffer from the effect of fuel dilution less then say a SAE60 (10w-60). Hope this helps . Cheers Guy.

Hi,
Saab recomend a SAE30 grade, either 0w/5w or 10w.
However these are really for economy figures and not hard use, I would go for really good 5w-40 full synthetic to give you greater hot end protection under hard use, it will also be able to take higher temps without shearing down.
Have a look at the Motul 300v or the SIlkolene Pro S.
Cheers
Guy.

Make: Volvo
Model: 850
Year: 1993
Engine type: 2.5 n/a petrol auto
Modifications: none
Driving style: fast motorway.
Any other information: The engine when cold is very tappety. It is also hard to start sometimes (poss low compression?)Our garage tried Mobil 1 which improved it slightly. The gearbox is quite clunky, and harsh. But maybe this is all normal, for a 180k car?
What recommendation are you looking for? Engine,Gearbox
Thanks for any advice, Roland

Hi,
Using a synthetic may well help to reduce tappet noise, espeically if it is ester based, being more fluid at low temps is probably why it helps the cold start a little, I would look at a 5w-40.
For the gearbox, it seems to be a withheld volvo spec but I believe it is an 80w-90, but I will double check on that, probably just a replacing the oil will make a huge improvement.
Cheers
Guy.

Hi,
For your Porsche we would suggest a good quality synthetic, around the 10w-50 grade would be ideal, this will cover everything from good cold start to plenty of hard use.
Brand wise, have a look at the Silkolene Pro S 10w-50.
Cheers
Guy.

After some consecutive -5/-8 nights my V70 sounded awful until the (freshly replaced semi synth factory spec) oil warmed uo and moved round a bit. Talked to the service manager and Volvo are just about to move to a very hi-spec fully synth 0w-40 oil (same as VW longlife?????) I'm just wondering about oil usage in "older" engines with the ow spec....... thatx for a (renewed) great thread. MoJo.

Mojo,
Some older engines dont like the 0w, and generally these have been poorly maintained.
For a well maintained older engine a 0w-40/5w-40 should be fine, consumption should not increase either.
Cheers
Guy.
