I've got a 2.8 V6 Cologne engine in a kit car. Engine originally manufactured December 1985 for a Scorpio automatic. Checked the bores when I first got the engine - no wear.Changed the oil pump and the valves - still running on leaded fuel (unleaded plus additive). Initially I used Duckham's Q 15W/40 and oil pressure was great (approx 50 psi) until the car had done a long motorway run when it dropped very low (oil light flickering and less than 10 psi indicated) on idle. A change to Comma 20W/50 hasn't seen any real difference.
Tried to stick with mineral oils as per lots of advice but it seems from reading this thread that I could just as well use a full or semi-synthetic. Any advice?
The car is used for fast road use.

Robin,
The V6 will be happy on synthetic, in fact if the engine is now in a kit car and gets used hard then moving to a syntheitc could be a good idea.
I would suggest an oil like the Silkolene Pro S 10w-50 ester/pao syntheitcs as a top option, due to the shear stability of the oil you should find that the pressure remains consitant, the mineral based oils will drop out of grade when very hot and under hard use, so what was a 15w-40 to start with could be a 15w-30 or lowever once it begins to shear down.

Hope this helps.

Top advise on this thread, hope the man in the know is still checking?
Anyhow, I've got an Audi S3 that has had it's engine replaced less than 3,000 miles ago, new turbo the lot and I was always using Castro SLX as recommended before the engine went. but I have noticed when the oil was changed after about 1,500 miles the Tuning company has put in Synta Gold 5W/40 according to the bill (Is this a VAG group oil?).
What would you recommend, for road use and ocassional very fast and daft road use.
Thanks for any help.
Hi,
What year is your S3?
And is it on fixed or variable servicing?
Cheers
Guy.

Hi Guy,
It's a 2000 - engine code APY 210BHP version
Fixed 10,000 mile service intervals, although after the engine change I think I will be trying to get the oil changed every 5k, just looking for what would be best, and a recommendation if possible?
Cheers,
Ok,
You are going to need an oil that meets the VW503.01 spec, this will be 0w-30/0w-40.
Brand wise, if you want the best then I would look at the Motul 8100 0w-40 as this is a pao/ester based oil which puts in the top quality bracket.
Next up I would look at the Fuchs titan supersyn sl 0w-30.

I've just purchased a load of 0-40 mobil 1 to put in my 993TT in the Autumn instead of the 15-50.
I also run a
vivaro 1.9 tdi (03 plate) (100bhp)
megane 1.5tdi (53 plate)(100bhp)
Would Mobil 1 be suitable for these also?
Briggs & stratton tractor / mower 1990 (13bhp) with 2500 hours on the clock - currently on mobil 1 15-50

Hi,
The Mobil 1 0w-40 is ideal for the Megane tdi, you may even find an increase in fuel consumption with it.
Who makes the Vivaro? not familiar with that one.
The mower, well not many poeple I know put Mobil 1 motorsport in the mower, but it will do no harm at all, in fact it probably loves it.

Here we go.........
Volvo V70 AWD 2.5 turbo, 106k what do you suggest??
cheers
Mojo.
Mojo,
You have some options.
As a cost option you are looking at a 10w-40 semi synthetic changed every 5-6k or so.
As a quality option a good 5w-40 true synthetic changed every 10k or so.
Volvo dont tend to approve oils so an up to date god brand oil is ideal.
Hope this helps.
Cheers

I would not suggest a full synthetic till the rebuild is complete. When you have rebuilt the engine run back in on a thick mineral oil, a good quality oil, then after 1000 miles or so drain and move to a full synthetic.
Not only would a full synthetic benefit the engine but the gear box is fed by the same oil so a good shear stable oil would help with the loads on the gear teeth.
Cheers

Do not use fully or semi synthetic oils in minis as i found out i had a brand new jack knight straight cut gear box which failed arfter 2000 miles this was then sent back to manafactuer who would not replace due to the use of the wrong sort of oil.[/quote]
Granted,
The gearboxes can be fussy and straight pao synthetic oils cause what you happened to you, however the gearboxes do like ester, so an ester based oil such as the Silkolene Pro R 15w-50 is ideal and well proven in the mini.
But on the whole you are right, be carefull with synthetics in the mini.

Mr Oilman
I have a 9500RPM 218BHP 1600cc wet sump race engine (or at least it is when I haven't messed up the intake system) and would like to know what oil you recommend.
Amongst the cars many problems are -
- Oil surge on slicks despite accusump and proper sump
- Head fills up with oil
- Oil pressure drops with oil temperature
Thanks in anticipation.
Can you give me full details of the engne, make, size and all mods that have been done.
Cheers
Guy.

oil man What do you think to the royal purple range of oils? i have been using it for the last couple of months with unbeliveable results and will now not use anything else, but i dont understand why they dont market in the mainstream?
Royal Purple.
There ok, American and use pao base stocks and some ester in a few blends.
All in all not bad on the quality stakes, I find it too expensive though once it has arrived from the USA.
We have better in Europe.

Make: Peugeot 306 XSi
Year: 1999
Engine size and type: 1998cc
Mileage: 29,000
The 306 has always been run on semi-synth 15w-40, as far as i am aware, i'm intending to use a fully synthetic on the next oil change, is this a good idea in this particular car? If so which viscosity would you recommend?
Much appreciated.
For the 306 the 15w-40 is really the basic option as these tend to be mineral multigrades, semi synthetics tend to be 10w-40.
As a top quality option your looking at a 5w-40 full synthetic for all year round use.
I have plenty of quality ones to choose from so if you would like a price list, drop me a mail.

Hi I have a VW Polo,
1.4cl
5sp manual gearbox
mk4
currently using 80w90 gearbox oil
I picked up the polo 4 weeks ago and once the box warmed up it became notchy. I had the oil changed and the Mech used 80w90. My new problem is this, when I go to use the car 1st thing in the morning it is very stiff n notchy untill it has done 10 miles or so. VW say that I should use 75w90 fully syn, but I don't want to go back to the old problem, people are telling me all kinds of things now so a little confused.
Any advice would be most helpful.
Thanks,
Ash
Ash,
The 80w-90's are very basic mineral gear oils, the reason it is notchy first thing is the oil is still very viscouse and throughout the winter this will be common, my fiat uno that I use to get to and from work, also suffers notchy gears in the morning.
You can trie and stop this by moving to a semi synthetic 75w-90 as this is slighty more fluid at cold temps, so hopefully eliminating the notchy gear change.
Hope this helps.
Cheers
Guy.

Make:- Vauxhall
Year:- 1992 (engine yr 1995)
Engine:- Corsa GSI 1.6 16v
Miles:- 6,000
Extras:- Jenvey TBs, MBE Eng Mgt (170BHP), 8000rpm rev limit, oil cooler.
I currently use vauxhall semi synthetic (I believe its 10w-40)and the engine is quite tappy. I'm silly and don't have an oil temp or pressure gauge so can't supply this info. I use the car for track days and i believe it runs quite hot. What oil would you recommend?
Cheers in advance.
p.s. I joined piston heads just to get this advice
Hmm well.
With that spec 10w-40 semi-syn is a no no. This oil is for stock road cars and really not up to the task.
I would look at a proper race oil like Silkolene PRO or Motul 300V.
An sae 40 of this quality will handle 120degC bulk oil temperature and an sae 50 around 145degC.
Personally I would try a 5w-40 first and see how the car likes it, if it doesn't then change to a 10w-50.
Look at Silkolene PRO or Motul 300V here: www.opieoils.co.uk/lubricants.htm

Yes, we have been experimenting with Silkolene PRO Race 0w-20 in a 550bhp Drag RX7 belonging to Dragon Performance. We have not done a real life run yet, purely testing but the car managed a 10.43 1/4 of a mile this year on 10w-40 so we are expecting much better on 0w-20 in 2006! We are hoping to be the fastest RX7 in Europe by next summer.
