I just put in the sougi s5000 this arvo, didn't change the filter though, was too lazy, will change the filter next service..
With the previous oil, when i ran the car, it didn't sound good, revving above 5.5krpm sounded rough..
With the new oil, i did some revving in neutral, nice and smooth, i like it, for under 50bucks, its a damn good oil, and at this price, i can change it every 4000kms. Driving around felt nice and smooth, but the exhaust was a tad louder...
