Re: General Servicing - Engine Oil
Section 01-3 of the owners manual the RS200 has a capacity of 10 litres in respect of engine oil:-
So 10 litres of a SAE 10w40 but I had to read up what that meant. Google explained...
"The Society of Automotive Engineers developed a scale for both engine (motor oil grades) and transmission oils. Viscosity is notated using the common classification “XW-XX”. The number preceding the “W” (winter) rates the oil’s flow (viscosity) at zero degrees Fahrenheit (-17.8 degrees Celsius). The lower the number, the less the oil thickens in cold weather. The numbers after the “XW” indicate viscosity at 100 degrees Celsius and represent the oil’s resistance to thinning at high temperatures. For instance, oil with a 5W-30 grade thickens less than oil with a 10W-30 grade in cold weather. Oil with a 5W-30 grade thins out more quickly at high temperatures as compared to oils with a 5W-40 grade. During winter and for cars used in cooler regions, your engine will benefit from using oil with low winter viscosity. During summer and in hotter regions, your engine will benefit more from oil with higher viscosity at 100 degrees Celsius. When comparing oils, it is important to take into account the location in which the car will be used. Thin oils that are less prone to thickening in low temperatures will help you start your engine more quickly in winter while thick oils that are less prone to thinning in hot temperatures will help your engine perform better in summer. As a result, 0W-20 and 5W-30 oils have been developed for colder climates while 15W-40 and 20W-50 oils have been developed with hotter climates in mind."
For the past few years my car had been using Mobil 1 10W60 "Motorsport Formula" which is a fully synthetic oil.
I found an interesting article and chart here https://www.motorstate.com/oilviscosity-htm/
So my dilemma is, stick to the handbook at go 10W40 or replace with what many performance cars go for and put 10W60 back in. I don't take my car on the track nor drive it to extremes so I want to get it right. Once again OPIE oils has come to the rescue:-

So given the advice I shall revert to the 10W40 the car was intended to use but I will say, fully synthetic options are a lot more limited (and expensive) so research on the type of oil is next...

After reading this I think given my potential compromise in viscosity I should make up any gap by sticking to fully synthetic and having read some reviews I have gone for Fuchs Titan Race Pro R 10W-40 Ester Synthetic Race Proven Engine Oil..
