As the title says this is the place for all oil related questions and hopefully over time it will build into a FAQ or reference point for others.

So, put your oil questions here but please give the following information if you would like a recommendation:

Make
Model
Year
Engine size/type

Any mods

Type of use (road/track)

Additional info (max oil temps, current oil used)

What do you want a recommendation for? Engine, Gearbox etc?

I hope this will help and become a useful thread

Regards
Simon

perfect glad you returned to saxp

Mostly motorway miles though expecting a few track uses this year

I need engine oil and would like gearbox oil recommendation to

Short Journeys to work everyday!
Im doing a few Santa Pod trips this year and also one or two track days!

Ideally i need a fast Road oil, But also something which will cover and protect my car on a day to day basis!

I think im using 5w 40 at the moment!

sorry its a 1998 s reg

Trackdays change the parameters as they are classified outside of the oil envelope for a stock recommendation, just like modded cars.

I would recommend Silkolene PRO S 5w-40 and Silkolene Silktran Syn 5 as the diff is fed from the gearbox

Check out the prices on my website as I have a sale on for 1 week in my Members Area.

Same as bove really although I forgot to mention that Motul 300V 5w-40 is also a good road/track oil.

Cheers

Paul,

Take a look at my reply to scott above

It's a mineral oil actually and not great quality.

It's not synthetic and is no thicker than any other 40 grade oil including 0w-40 or 5w-40

They are all 14cst viscosity at 100degC and 40 times thicker at 0degC

Cheers

A short lesson on Multigrades:

If you see an expression such as 10W-40, the oil is a multigrade.

This simply means that the oil falls into 2 viscosity grades, in this case 10W & 40.

This is made possible by the inclusion of a polymer, a component which slows down the rate of thinning as the oil warms up and slows down the rate of thickening as the oil cools down.

It was first developed some 50 years ago to avoid the routine of using a thinner oil in winter and a thicker oil in summer.

For a 10w-40 to attain the specification target a 10W ( W = winter) the oil must have a certain maximum viscosity at low temperature. The actual viscosity and the temperature vary with the viscosity grade but in all cases the lower the number, the thinner the oil, e.g. a 5W oil is thinner than a 10W oil at temperatures encountered in UK winter conditions.

This is important because a thinner oil will circulate faster on cold start, affording better engine protection.

For a 10w-40 to attain the other specification target a 40 oil must fall within certain limits at 100 degC. In this case the temperature target does not vary with the viscosity grade, if there is no "W", the measuring temperature is always 100degC. Again the lower the number the thinner the oil, a 30 oil is thinner than a 40 oil at 100 degC., which is typical of maximum bulk oil temperatures in an operating engine.

The engine makers are, of course, very well aware of this and specify oils according to engine design features, oil pump capacities, manufacturing tolerances, ambient temperature conditions etc. It is important to follow these guidelines, they are important and are an are stipulated for good reasons.

If the engine has been modified, the operating conditions may well be outside the original design envelope. The stress on the oil caused by increased maximum revs, power output and temperature may indicate that oil of a different type and viscosity grade would be beneficial.

coming up for 90k miles

motorway and town miles, 300 average every 10-12 days 12k ish yearly, rough starter in the cold. Just something to keep her in good nick and running well for as long as poss and start better on a cold morning! cheers

the only problem with all of this is it appears that your more sales orientated than individual product/application, unless multiple manufacturers models and cars fall in to the same categorys (I see your posts on alot of forums i read) The only reason I say this and your quite within your right to correct me, but ive asked twice about my particular car and application and ive had 2 seperate answers and reasons, where as 1 I agree with the other was more err sales...

this would be simon and guy btw...

straight to the point!..

We use a proprietory database to source information on all cars back to 1980 (in fact the same one as used by Castrol, mobil and many others).

The information is going to be pretty repetitive in what is recommended particularly in most cars post 1990 as the OEM's are all moving in the same direction grade wise except for maybe the likes of BMW and VAG who are moving towards 0w-30.

Yes I am bound to recommend the products that I sell, they are the ones I know intimately although selling 6 brands does give me more scope than most out there.

More importantly I know the quality well and can advise on some other brands where I have chemical analysis.

We are on 300+ forums so you will bump into us from time to time no matter what car you have.

Honest answer like it or not

Cheers
Simon

This has the 1.6vtr Saxo engine in an ax, correct?

What do you use it for road/track etc?

Cheers
Simon

What viscosity (grade) oil are you using at the moment as it could account for poor cold start.

Cheers
Simon

i just use normal oil from my local motor factor (to citreons hand books spec), i have 93000 miles on the clock and its never missed a beat and she slighty modded. Ive had her since she had 35000 mine on the clock and my bro did the serives on her after the warranty ran out because the car belonged to his mate. i work on the theary(sp)avarage quality oil and 3000 miles changes. but every ones differnet.
