Oil Advice and Recommendations Here

[opieoilman]

Pheonix,

I had a look at your profile and webiste, all I can say is holy sh#t!!! is that thing for real???

The oil I would suggest is the Silkolene Pro R 15w-50 ester/pao syntheitc.

Tech data here www.opieoils.co.uk/lubricants.htm

With an engine like this, I have also contacted the technical team and chemists at Silkolene to see if they can add any other recomendations for you.

Cheers

Guy.

Thanks Guy.

Yup she's foreal. 6 weeks to go before things start coming together.

Excellent, email me offline with the Silkolene recommendations.

Still here and watching if anyone needs advice.

Advice on S6 3.6L currently at 8000 miles,
Handbook recommends 0W-40 fully synthetic Carlude triple R for 6000 miles and on.

At last service TMS put in Castrol formula RS but it does state what grade.
I did notice after the service however oil P had risen from 8 - 15 psi at tickover depending on temp to 13 - 25 psi

and risen from 48 psi to 54 psi at high revs

Any thoughts appreciated

[opieoilman]

It sounds like they put RS 10w-60 in which is way out of grade.

The viscosity difference at 100 degC are as follows:

sae 40 = 14cst
sae 60 = 24cst

This would account for the higher oil pressure.

I would make further enquiries about this.

Cheers
Guy

I just looked up the figures and I can't find the Carlube 0w-40 but it will be a typical 0w-40 from a viscosity point of view so here are the differences.

Castrol RS 0w-40

@40degC = 73.5cst
@100degC = 12.90cst

Castrol RS 10w-60

@40degC = 159cst
@100degC = 22.70cst

These would account for the oil pressure differences unless I'm mistaken!

Just been told by the lady on the service desk that they use 10W - 60 Castrol formula rs on all tvr servicing. Can you give me technical info for back up for when i phone them tomorrow please, ie pros and cons and what i should change too.

Many thanks

Not sure why a dealer would use 10w-60 when tvr recommend 0w-40

I can't understand what posessed them to do this.

If the handbook says 0w-40 then use a 0w-40 (Castrol RS 0w-40 or M1 0w-40 are readily available) and stick with it.

The difference is at both ends of the scale.

10w is poorer cold start than 0w and the sae 60 is just too thick which will cause excess friction and heat in the engine. Both factors cause more wear long term.

Just read through an earlier post think it was by powerlord also talking about similar oils used on speed 6. He phoned tvr and apparantly they stated that they now recommend 10w - 60, so i'd have no comeback on the dealer.
I'll phone tvr in the morning and see what they say

[nickfb1]

Just spoken to tvr and apparantly they do now approve 10w - 60 for use in the speed 6. your thoughts?

[opieoilman]

My thoughts are that its apples and pears here, they're completely different.

I personally wouldn't use thicker than a 10w-50 and would look at a 5w-40 in preference. They should be decent synthetic ones of course.

Remember RS 10w-60 is not a true synthetic, it's petroleum based.

The place I have been taking my chimarea 450 uses Shell Helix Ultra 5w 40, which from what I have been reading would appear to be a bit thin. Thier view is it offers better cold start performance. I Have a leven cooling kit installed which keeps the running temp to a maximum of 85 degrees and I change the oil less than 3000 mile intervals. No oil pressure or excessive usage problems.
I would really apreciate your view on this.
Many thanks,
Gareth.

[opieoilman]

5w-40 is fine as long as you're getting good oil pressure and not excessive usage.

The benefits of low viscosity oils far outweigh the benefits of using a thick oil everytime.

Better cold start = less engine wear

More BHP at the wheels

Better fuel consumption

Low viscosity oils dissapate heat better

opieoilman - would appreciate your comments on the T350 forum at the moment disussing engine oils for the S6. lot of differing views about 10w-60

cheers

Full rebuild 7000 miles ago with alloy timing gear,polished ports, new cam and unleaded heads
Now starting to loosen up and easily revs up to 5500rpm after lengthy running in for first 5000miles
First oil change at 500 then every 5000
Oil used

It uses about 1pt every 2000miles and runs at 55lb and tickover at 25lb.
Is this oil and the change period OK

All seems fine to me.

The Valvoline is a semi syntheitc and is ideal to finnish of the running in process, you could use a good quality full syntheitc if you wished to improve on quality and increase your drain intervals, also a good idea if the car is driven hard, if not then you will be fine as is.

Many thanks for that.

opieoilman said: s2art said: One thing that has not been emphasised here is the importance of the smaller number eg 5w 50, with respect to the speed six. As we all suspect a top end lubrication issue when first starting the engine the smaller the number the better. This is particularly important in winter. Are there any 5w 50's or better still 0w 50 oils out there any more? I would have thought they would be far beter than a 10w 50. Yes this is important to a point, 5w is better than 10w etc for cold start. However the numbers are extreme for UK Climate. To meet the 0w test an oil has to pour at -35 degC and for 5w -30 degC! These temps are brass monkey stuff, 10w is fine for UK and most European climates. Cheers Guy This is misleading at best! All oils will pour at any temperature, it is the speed of pour which is important

Not strictly true. Oil will freeze as I'm sure opieoilman will tell you.
