I went to do another oil change on the weekend and found that Castrol EdgeSport is no longer. It has been replaced with Edge Titanium .....and Edge Titanium appears to be crap!

I took a punt and used the Edge Titanium on the recommendation of the guy at SuperCheapAuto, he said it is the new version of EdgeSport. But instantly after the oil change the car is now making more lifter noise than ever before, even with 4000km old EdgeSport it was quieter. The rattle fades after warm up but is still there faintly all the time. If I drive through a tunnel or next to a wall I can hear it clearly.

I think I might cut my losses, dump this Edge Titanium garbage and try the Shell Helix 5W40.

Any other recommendations? I don't mind paying $$$ if it's worth it.
