Hello all,
See attached my recent UOA on Valvoline Restore and Protect in 10w40 (left).
Comments:
- The previous UOA was Mobil 0w40;
- The purpose of this UOA was to check for coolant intrusion as the vehicle had a thermostat issue about 6 months earlier;
- This is the first change with R&P - the oil was notably darker than usual
- In the intervening period between UOAs, I have also been adding a small dose of 2 cycle oil to the fuel. Cylinder wear has decreased, but note the UOA was taken at 3000km not 5000km.
- Theres no doubt that 0w40 mobil is incredible oil and I will be reverting back once the "cleaning" is complete
