OK ... did an oil change this weekend. Switched to Royal Purple 10W30 with an RP Extended drain oil filter. Did some reearch and was interested in the Synerlec additive package in RP so decided to give it a try.
First off the engine is less buzzy than before especially at idle on startup, not surprising since I was using RedLine before and RL is known to make engines sound louder. Noted that it was not as quiet as Mobil 1 but then I was running the wrong weight - 15W50.
Initial drive on hiway felt very good, engine revs free and actually is getting quieter ... engine feels a tad stronger .... power comes on a little better causing a downshift whereas before the car would just build speed in the same gear. I'm not expecting any great differences and the oil will probably need 2-3000 kms for the additive package to work in well. Intending to run this oil for 10000kms.
While some of the benefits of RP is lower operating temp and better mileage not sure if I'll notice them. I have a fully functional thermostat so my engine operating temp will be fixed. As for mileage I will check this at the pump, however, since I'm not running a fixed test loop this may not provide any useful information.
I liked the purple color of the oil, made it easy to check oil level, unlike the Redline which is extremely clear and hard to see on the dipstick. Unfortunately the color has almost gone and the RP is also a very clear oil.
Some of the things I wouldn't be able to notice is engine cleanliness and wear protection, so I think I'll keep a sample for a UOA.
Well that's it for now, will update between 2-3000kms
