Are the hydraulic lifters cold start up minor noise in winter just 3 secs is normal .... i compared it with a collegue's 1KR-FE with 5W-30 which has 7/8 secs approx double delay than mine before it becomes smooth?
Mine as you know is 0W-20....
Another info as per our technical research, practically we both felt considerable diff in paddle response of both almost at same mileage i.e. 30 to 35k kms. He commented my 1KR-FE to be more zippy and peppy as compared to his which i felt the same way....
I am sure its the slight diff of lube oil viscosity grade as we use same Total quartz 9000 SN GF5 from same source.
