hi people i'm looking to do an oil change soon and was gonna use Fuchs TITAN 10W-40 Full Synthetic.
I've got a Subaru Impreza 1999 turbo 2000 mods are 200 cell sports cat, non resonated middle section and P1 back box only running at 241 bhp atm but will this oil be ok or shall i go more towards 10w50 or 5w40???
thanks everyone

Excuse my ignorance but is that stuff a motorbike formulation? If so, it's probably got friction modifiers to suit wet clutches. Whilst it's usable why would you use it when there are loads of car engine specific oils available?
10/40 or 10/50 is fine for your engine.

na it says in the description it for cars high performance petrol or diesel engines mate didn't say anything about it being motorbike formulation or anything and what brand of oil would u recommended mate??

Coppin1991

i was thinking maybe Mobil Super 2000 10w 40 part synthetic as my car has done 120000 so its pointless to use fully synthetic oil

Hi

Unless you use the car on track a lot, the 10w-50 is a bit thick for your car and I would go for a 10w-40

http://www.opieoils.co.uk/c-657-10w-40.aspx

The best ones are the Gulf Competition, Motul 300V, Redline and Millers CFS. Fuchs Unimax Ultra MC is a good mid-range option. As a cheaper alternative the Fuchs Syn MC, Shell HX7, Motul 6100 and Millers XSS/Trident are good choices.

Cheers

Oh ok no I don't use the car on a track it's just my everyday car mate I don't think Fuchs Titan race s make a 10w40 but I've heard a lot of good things about miller CFS oil might go for that option mate 10w 40 fully synthetic millers CFS
Thanks for the help people

Yes, the Millers CFS 10w-40 will be ideal.

Ahh................I see you removed the 'MC' from your original post! It was that, that got me thinking.

Brilliant thanks oilman when do u think it would be a good idea to use 10w50 oil as I hopefully in the future looking to modify my car to about 300 - 350 bhp will I still need to use 10w 40 then or switch to 10w 50 at that point?

Coppin1991

Yeah sorry about that john I must have copied and pasted to much of the item I was looking at I was only supposed to copy and paste Fuchs Titan lol that's my mistake mate but thanks for pointing it out for me people must have thought I was mad when looking at it first time lol

That oil is a car oil, Silkolene is the bike oil division of Fuchs. The MC stands for Molecularly Converted, meaning that the oil has been through a process called hydrocracking.

Cheers

Coppin1991

Oh ok so does that mean MC is better oil or it just mean is been through a different process

Hi

it means that while it's sold as synthetic, it's actually made from mineral oil that has been refined and modified. If you have a look at this, it explains it.

Assuming you're in the price range, why not Fuchs Titan Race Pro S 5w-40?
Wouldn't the 5w be beneficial on a daily driver?

Coppin1991

Well I hear a lot of people using the 5w 40 fuch Titan race s in the uk turbo 2000s but I thought 5w40 is only really beneficial in winter weather mate but I'm not sure if that's 100% correct just what I have read mate

Hi
Be interested to read Oilman's answer.
Bearing in mind we're discussing Fuchs Titan Race Pro S:
Why 10w-50 for track days, when 5w-40 would increase your bhp, and provide enough protection.

Hi

The 5w-40 is probably going to be 100% fine, but a few people have mentioned that their older Imprezas are very noisy with a 5w-40 for cold starts. A 5w will still give better protection for that, but people often think there is a problem if their engine is noisier.

If the engine is modified, so runs hotter, a 10w-40 can get too thin on track, making a 10-50 a more suitable choice. Okay, a 0w-20/5w-30/5w-40 can lead to increased power, but it can also cause insufficient protection. In a race car where every bhp matters, running a thinner oil can be beneficial, but for someone's road and track car, I would say protection is the important thing.

OK. What temp is too hot, for the pro s 5w-40, if you're monitoring oil temps?
I wouldn't start to get jumpy till 115 degrees - aren't synthetics stable to 140 degrees?
When using an external oil cooler, what temp would you like to see the pro s 5w-40 kept under?
What would you gain, temp wise by using the pro s 10w-50? Or is the 10w-50 just giving you a safety margin, if your not monitoring oil temps?

After some searching:
2500 miles plus 1 trackday can reduce your viscosity by 20% - Doing a trackday? Change your oil!

oilman

Hi

Yes, that's answered it pretty comprehensively. Fuchs recommend changing the Pro S after 10 solid hours of track use, although we have had sponsored drivers and customers using it for 24hr racing. One trackday should only affect your oil that much if your car is causing fuel dilution or the oil isn't that good to start with. Oil companies will often suggest changing oils earlier than necessary as it should still be well within the safe tolerances meaning that they can't be blamed if something goes wrong and also it means you go and buy more oil.
