Oil advice and recommendations here!

[danwebster]

Thanks a lot for that, i will most probably try that on the next oil change.

I run a competition oil pump in it, but over 7000rpm the pressure starts to tail off little, dropping to maybe 50psi from the 65 it normally runs at.

My brother also runs the same angine as me, although with hairier cams so his produces 185hp at 8600 and revs to 9000rpm, so he will also be grateful for your comments.

On a side note, the castrol R4 did smell lovely when hot!

Guy,

Any views on using the Castrol High Mileage (for more mature engine) oils based on these specs

Paul,

Just went and had a look. The higher mileage oils sometimes contain addatives to make the oil seals swell up a bit and maybe a few extra detergents.

Having a look a the specs the most important one to look at the pour point and flash point, this will give an indication of base stocks used, on the face of it they look like the same oil with just an extra addative of two to affect the pour point of the 5w-30 high mileage.

We have also found a lot of it is down to market reaserch, put on the can "high Mileage" and all high mileage owners will buy it, so you know what percentage of these cars are buying your oil, same goes with "Diesel" most oils do both so its just another market research.

Cheers

Guy.

I thought "diesel" oils contained more detergents and stuff to cope with partly-burnt fuel residues?

Hello again

Is Silkonene Pro R of similar performance to Mobil 1?It seems to be full ester, which I take it is a good thing.

Silkolene also do a Pro S, do you know where that fits in their range.

Thanks again,

Shane

The Mobil 1 15w-50 is a pure PAO synthetic and does not contain Ester, the Mobil 1 are at the top of the game for straight PAO oils in my opinion. The Silkolene Pro R 15w-50 has Ester/PAO base stocks, also has a little mineral added (not base stock!) so it can be used in a larger number of engines going back to some vintage. The Pro S is a Ester/PAO and has no mineral added so is a pure synthetic through and through. In my opinion both the Pro R and Pro S out perform the Mobil 1 but it is close on their heels.

Hope this helps.

Cheers

Guy.

What oil would you recommend as a running in oil for a RV8 5.0 TVR Griff, new pistons, rings, honed etc. Basically standard spec other than a slightly upgraded cam ?? And how many miles before it should be changed and what oil from then onwards ??

Many thanks.

To run in an engine you want to use a good rich mineral oil around the 20w-50/15w-50 grade and give it some stick for around 1000 miles.

Once the run in is complete I would personally use a full synthetic either PAO or Ester/PAO. Keep it thick and go for around the 10w-50 or 15w-50 grade, dont bother with 10w-60 its just a little too thick.

Cheers

Guy.

Thanks for that, any particular brands you would recommend ?? I've looked on the labels of various oils and they never seem to say they are a full mineral. The oil manufacturers seem to only want to shout about synthetic oils. I want to get the running correct this time, as it seems I may not have done the first time.

Thanks again.

Wixer,

No problem, e-mail me through my profile and I will forward some brand options on to you.

Cheers

a bit late to this one... but i want to do an oil change on my recently purchased Golf R32. Its done 10k miles and according to VW, not due for a service/oil change until 20k. My handbook tech data does not even cover the R32, so i don't know what oil to use. The help i got from VW service reception was that it needs 'special oil'!!

Any help appreciated!

Thanks

rob

Rob,

If your car is on fixed service intervals than it calls for an oil than meets VW502.00 spec, I think check with your handbook on this one but it will be a fully synthetic 5w-40

If the car is on variable service intervals than you will need a 0w-30 oil that meets the VW503.01 I again think, you will have to check your handbook.

The variable service is when your car tells you it needs a service, could be 10,000 miles could be 20,000 miles.

I hope this helps.

Cheers

Guy.

Hope this helps.

Thanks very much Guy.

I don't really know if my R32 is variable or fixed servicing. I have a nice leather bound handbook with an R32 badge on the front, but no tech spec for the R32!

What are your thoughts on 20k miles between oil changes?

PS, Just had a word with a VW mechanic who informs me the car is on fixed long-life servicing and needs VW506.01 - 0W-30 oil and they use Castrol SLX. He intimated that most people don't leave it that long before changing the oil. Think i will put it in for an oil change, although they want £96 for the privealige!!


Cheers

Rob

Rob,

That sounds about right, if you put your car in for an oil change it can be done cheaper. If you take in your own oil they will change it for you, and you wont have to buy it at their prices!

However according to my records the Castrol SLX 0w-30 does not actually meet the VW506.01 spec. The Fuchs Titan Supersyn LL Plus 0w-30 does and as a note was used for the original factory fill on the engine. Dealers only use the Castrol usually because they have signed some kind of deal.

Hope this helps.

Cheers

Guy.

Overview for OCI

LongLife Regime.
To obtain the most benefit from the LongLife service regime, the car should to be generally driven in a style/condition of use listed below
• Mainly longer distance journeys.
• Limited number of cold starts, engine is kept at operating temperature over a longer period of time.
• Daily mileage above approx. 25 miles.
• Constant speed.
• Vehicle used regularly.

Time/Distance Regime.
It your is driven in a style of use listed below, it may make sense to opt for the Time/Distance regime.

• Extremely uneconomical driving style ie continual maximum acceleration ie "foot to floor"
• Vehicle fully loaded
• Mainly short journeys.
• Frequent cold starts.
• Frequent hill climbs.
• Frequent towing.
• City Centre driving

Paul,

Well put.

I would be inclined to go for the fixed service for peace of mind.

Cheers

Guy.

He sounds a bit confused... 506.01 is a diesel spec for variable servicing, variable servicing for petrol engines is VW spec 503.00. Fixed servicing for petrol is VW 502.00 / 501.01 / 500.00. Castrol SLX Longlife II meets both petrol and diesel specs for a variable service but not the specs required for the fixed service. Similarly, Castrol Formula SLX should not be used for cars on variable service (but it does meet the 502.00 spec)

edit: Having said that, for the R32 on fixed service, it says that a 10W/15W-40 is suitable, even tho Castrol Formula SLX is a 0W-30. It then says that for variable service, a 0W/5W/10W-X is required, even tho they are the same engine, just on a different service schedule...

Great info, thanks Guy(s)!

Car is in getting 10k service and will be drinking 5W-40 Quantum Synthetic oil on fixed servicing.
