My Jazz is coming up to 40k service and I decided to do it myself to save a bit of money. I came across an engine oil Valvoline SAE 10W-30 API SM/CF ILSAC GF-4 which is a low viscosity synthetic blend oil. According to the user manual it is fine and it may provide some saving on gas as having low friction.
Is there any issue with this engine oil in the Jazz???
