We now have a number of PF Members using Silkolene PRO S 10w-50 or 5w-40.

We are looking for some technical feedback on the performance/differences that you have noticed since switching oils.

How does it compare?

What are the differences?

Is it better and why?

Thanks in advance,

Cheers
Simon

 

i have nver used it, but i just swtiched oil form Castrol RS 10/40 to Agip Fully Syntheic 10/50 and it is too thin - makes my car sound like a 1100cc fiesta on cold startup

how much is this stuff anyway, inc postage.

 

its the dogs on my S13

 

oilman, just started using it on my 4x4 sapph (was using Mobil 1 m-sport), too early to say I am afraid.

 

i got some silkolene pro s 10 50 off stu to try. i have always used castrol rs 10 60 but i wont be going back on castrol.

the car sounds much better on silkolene especially on a cold start and the engine feels to be looser if you can understand what i mean. its a fairly new engine build approx 5k so will be loosening up more with use but i could tell the difference as soon as i put the silkolene in it tends to rev much easier and still sounds quiet even after 30 mins of hard driving which suggests to me that its withstanding the heat generated.

the other good point is you get 5 ltrs instead of 4 ltrs so if you need to top up between oil changes you dont have to buy more, although i havent had to top up between oil changes yet.

 

I am using Silkoline PRO S 10W-50.........

a. Deffo slightly better performance (feels like a few extra BHP)...

b. Better oil pressure hot and cold, especially at idle after a hard run (on Es Coss oil guage)....with the previous oil (Castrol RS 10-60) the pointer would be just on the red zone at idle after a hard drive BUT with PRO S it is 3-4mm off the red zone.

 

How much is this? and is it only on special order or can u get it from Halfrauds etc?

 

only cossie owner replies.. so would this stuff be OK on an RST. Currently using mobil motorsport, but a change for the better cant do no harm

Is this thicker or thinner that mobil motorsport? not that clued up on oils

 

It's way too specialist for the likes of Halford.

It's on offer until 10th May @ Ł27.50 for 5 litres plus carriage.

Our list price is Ł32.49 plus carriage

Retail is Ł45.00!

You need to call or email me (01209 215164) sales@opieoils.co.uk

Well,
Ive always dissliked Castrol RS in the YB and CVH Turbo as many old school forum members will remember as ive had a few heated discussions about it causing follower rattle on Hydraulic Fords (Whatever happened to Andy? That argument was legendary.. top man ) I dislike both its cold thickness and its hot viscosity when not used with an oil cooler. Ive always been convinced it is NOT what it says on the tin.. Its deffo not made by Ronseal

I do however love Mobil 1 motorsport and have used that in customers cars for many years unless specifically asked to fill with RS (Some people request only that, so i do as im asked)

After a chat with Simon at Opie i took delivery of some Silkolene Pro S 10w 50 and tried it in my own YB for a while.. results?

This Pro S appears to be better when cold and better when VERY hot for the YB. In fact, i concur that engines ive drained of RS10w60 and refilled with this oil appear to have gained a few noticeable Gee Gee's. I put this down to the frictional losses dropping within the engine now its having an easier time pumping the oil around. I dont believe it protects any better or worse that M1 MS but im convinced its far better than the RS10w60.

With regards the pumping pressures of 10w60, i have noted over the years that most of the oil pump driveshaft failures ive seen and heard of that have wrecked engines were running this hard to pump 10w60 RS as well..

Final 2 comments:
1) Its red. Sound a daft point? Its a great point when your oils always clean and you cant see it in low light on teh dipstick

2) It comes in 5 litres. Bargain IMO.

Hope this is the kind of feedback you wanted and im not just waffling.

 

It's a 5w-40 or 10w-50.

The 10w-50 is the same thickness as M1 at 100degC but has better cold start protection when you turn the key. This is important as 80% of the engine wear occurs on start-up.

Depending on oil temps, you may be better using the 5w-40 as this if perfectly fine up to 120degC.

Cheers
Simon

 

cheers Simon.. what are the majority of RST owners buying? tempted with the cold start protection

stu - detailed reply never realised it was red

 

You can use either but if it's highly modded and used in competition then the 10w-50, if it's a nice stock daily driver then 5w-40.

Cheers
Simon

 

daily driver which is fairly standard

Will check out your thread in the traders for P&P costs

cheers mate

 

Just bought some Silkolene from guy.... not used it yet so all I can say is nice packaging

It will be in the car in two weeks time so we shall see

I was very impressed with Guy who I dealt with though and delivery and prices were AWESOME. (bought some Mobil 1 from you as wel

 

think i need to order me some 10/50 then - damn current oil has only done about 200 miles and i dont like it

 

Mines going in tonight on my new engine sounds promising

 

i use the PRO-S and can honestly say it is excellent.my car runs about 230bhp and gets used very little with sometimes a couple of weeks passing before being used again. on these occasions i would always get rattle from the top end, be it followers , rockers or whatever, but since switching to PRO-S i get no rattle at all. i recently took the car off the road for about 5 weeks and when i started it up it was rattle free i have also noticed slightly cooler running temps. also before with the old oil if the car was driven really hard it would always sound like it had been driven hard when you stopped ( if you know what i mean, the engine was slightly louder and more rattly ) but now it just sounds smooth and spot on.

also love that it's red

 

Thanks so far guys, knew you'd like it.

GO SILKOLENE

Cheers
Simon

 

Never tried it, but want to use it next oil change - but I had to break into my Castrol RS 10w60 oter day cos loosing oil - from turbo drain

Ah well

 

Hmmm i got a tub of Castrol RS sat in my garage, a cossie that needs an oil change, 2 months of use which the car is going to have now what do i do

 

Go it ready at home to go in !!

Will let ya know....

Al...

 

ive been using castrol gtx in my na tuned 2.0 zetec. Would this oil be better for me .

 

Stu - what u think of valvoline racing 5-50?

My oil temp rarely goes above 190F so far, so a thinner oil is probably better.

 

I got the Pro S 10w50 off a dealer over here in Belgium and I just had it put in my car.
When I'll FINALLY get my car back, I can test the stuff.

Coming from Castrol RS 10w60 so should be good according to you guyz.

 

Simon do u know any company in holland that should sell it? as i'd like to try it sometime prefer the closest to Haarlem

 

Rene,

Where in Holland do you live m8 as I can get you some.
I'm close to the Dutch border (Eindhoven).

 

You live near Harlem Reno?

Fook that was on of my back up choices for uni if i didnt get in to Tampa

 

Haarlem Rice not Harlem LOL


Geert that would be Haarlem as well near amsterdam so about 130 km's from eindhoven

 

but Haarlem sounds like you got a stutter U live there then faggot?

 

F**K off then and try and find your own.

 

thanks for the offer though

 

sorry i dont talk like you do actually i dont i live on a park bench in las vegas just saying for fun that i live in haarlem

 

when i say this, want a ohnest answer as to be truthfull i cant be botherd to study the ins and outs of oil rather leave that to the experts!
but would you say its worth changing over from mobil 1 motorsport to this in my ERST

 

If you really want some and you can't find any, then just let me know m8 and we'll work something out.

 

thanks mate appriciate it

 

Red coloured normally means bike oil...ie good for transmission and engine.

My Duke runs Castrol R4 superbike

My Cossie runs Mobil 1 Motorsport

My 2 strokes always ran Sikolene Pro2 VERY impressed...so may have a go on this Sikolene oil in my new build

 

PSML your not all there Reno

 

Yes, definately!

Cheers
Simon

 

All good feedback so far then
