My MR-2 is my second car, I plan to do 2-3 track days this year and use it a few times a week on the road.
I know it probably doesn't matter as it's just a Corolla engine, but I'm struggling to choose the oil. I have the following on my list:
Castrol Magnatec Stop-Start A5 Engine Oil - 5W-30
SPECIFICATIONS / INDUSTRY STANDARDS ACEA A1/B1, A5/B5 API SN ILSAC GF-4 Meets - Ford WSS-M2C913-C / WSS-M2C913-D
Shell Helix Ultra Professional AF 5W-30
Specifications: API SL, ACEA A5/B5, Ford WSS-M2C913-C & WSS-M2C913-D, Jaguar Land Rover STJLR.03.5003 (meets the reuqiements of)
Petronas Syntium 5000 AV Engine Oil - 5W-30
Specification SAE 5W-30 ACEA A3/B3/B4 ACEA C3 Performance API SN VW 504.00-507.0
Petronas Syntium 3000 FR Engine Oil - 5W-30
Specification SAE 5W-30 API SL/CF ACEA A5/B5 FORD WSS-M2C913-D RENAULT RN0700
Or should I seek out a 5W-40 ACEA A3/B4 (already using Shell of this spec in my other cars so could be convenient)? Is this better considering the abuse the engine will take on track?
I don't plan to have a dedicated track oil so whatever is in there will stay in there for 6 - 12 months.
Thanks in advance
Edit: for UK climate
