I bought the oil because Giant was doing a stock clearance sales selling at RM 80 (where to find full synthetic at RM 80) so I decided to give a shot.
FC so far is almost similar as my ex 10w-30. So that's a good sign. Cause I've tried once 15w40 HDEO diesel oil and FC was worse.
Being turbocharged it should withstand the extra heat and extra abuse (turbo addiction). Furthermore my car manual says recommended 10w30 but 5w40 oil appears "lower temperature range" in the manual compared to 10w30.
Would like to hear from others whom used this oil. I know it's too cheap to be true but if it's from Bosch what could go wrong.
As fully synthetic, it is known that it have higher temperatures limit vs mineral, hence no problems for your turbo campro engine.
