This is just a personal observation. Earlier on, some people claimed
after the first service, their cars were more responsive. Having just done my first 1K service, I have to concur that the car does feel distinctly preppier.
Unlike initial thoughts, this
improvement wasn't caused by a ECU remap. Rather it was a simple oil change to one that's presumably less viscous. The car is more willing to rev and
feels more powerful. There is however a downside. Thinner oil also equates to a noisier engine. With the new & less viscous oil, when we experience engine braking the sound is more audible. Hence some may even mistake this sound as a 'feeling' the car is jerking. Odd how a simple oil change can have such an pronounced effect.
Now do you understand why some of us are crazy abt engine oil brands, viscosity, lube type (FS, mineral, etc). Lube lubricate the piston and other major parts of engine...the heart of it. Thus using different lube on different engine usually provoke DIFFERENT response, some good, some bad. Best and most expensive lube does not necessary means the best for certain engine.
CFE uses weight 30 for balance performance and fc. Run A LOT of HIGHWAY at highspeed, weight 40 might be more suitable. Always jalan in city, 30 is the best balance lube for now. FS USUALLY has less vibration on engine being smoother and of hydrocracked refined mineral oil but it might not give better performance than lets say mineral. It do has less contaminant in its lube (refined mah), thus lubricate better and stays a wee bit longer than mineral. Mineral and semi for me is almost the same.
