10w50 oil.
Anyone use 10w50 oil exclusively ? I know RCM and scoobyclinic recommend 10w or 15w oil this goes against Subaru's recommendations, but one would argue that RCM and Scoobyclinic know more about these engines than most....
My car is a JDM Forester EJ205 Turbo, 230PS year 1998, 50000 miles engine is the same as the WRX, ..........would 10w50 be OK or just stick to 5w30/40 ?

all depends on use and spec of the car more than sticking to something aimed to achieve a min. service requirement and in general keep costs as low as possible to satisfy the Lease / Fleet market when new............
in general terms a good quality (ideally full synth) 5w40 would be the min recommend with a 10w50 being more suited to aggressive use or a highly modded engine - 10w60 or 15w50, etc. "may" be beneficial in certain applications

Forgot to say mine was forged. Usually use black Subaru filters but have just got a couple of the RCM filters so gonna try one of them next time. Heard really good things about them.

in all honesty John I really don’t knowA member off of here I have forgot now who it was,sent me a link to a fella on Facebook who supplies it and has been using it for years now.I do my own oil changes but at the time I could not find a stockist for it,I then heard that Scooby Clinic was stocking it and using it in their race cars and that they rate it highly...My car is booked in with them later on this year so I will get a few oils changed then.SJ.

I am hoping this link will work as it is the technical details as to why it is better than the other stuff
(Moving from Fuchs - have seen a drop in oil temps on the track which is no surprise)
If the link does not work look up - Silverline Synionic on Facebook and the PDF is on there.

The new ‘Race Specification’ range has been developed from our existing range – which was already able to out-perform the vast majority of ‘competition’ lubricants with regards to friction reduction and film strength. In the case of the latter, Synionic has been independently proven to have film strength up to 50 times higher than some of the best-known ‘name brand’ race oils anyway!
What are the Benefits offered by Synionic Lubricants?
•Reduction of “friction horsepower” equals a gain in actual torque applied to the work.
•Reduction of friction equals a decrease in actual operating temperatures.
•Reduction of temperatures equals a decrease in actual running temperatures.
•Reduction of the oxidation rate equals a decrease in the corrosion tendencies within the system.
•Reduction in friction equals smoother and quieter operation, with less stress to the engine or equipment.
•Reduction in friction equals greater mechanical efficiency, which could mean better fuel efficiency or lower electrical usage.
•Reduction in oil temperatures equals a decreased loss of viscosity, which results in better hydrodynamics and less oil consumption.
•Reduction of friction, and smoother metal surfaces, equals improved seating between piston rings and cylinder walls, less oil consumption, less leakage of combustion by-products from combustion chamber into the lubricant system, less wear of metal surfaces and possibly a decrease in compression loss (less blow-by).
•Oxidation inhibitors and dispersants keep your system clean and free from contaminants such as carbon, sludge, resins, varnishes, etc.
•Reduction in oxidation and contaminants

Are they giving a spec sheet for their race spec oils yet? https://synionic.com/ I can't seem to find the race spec oil on the official Synionic website?s a
