Anybody use rotella t6 5w-40 on a 06 jetta tdi pd. I am a newbie with a new to me 06 jetta tdi. 174k,5sp..i found out old owners shop was putting a 5W-30 synthetic. I changed oil with the rotella,figuring it was right weight and full syn and torbo diesel rated. Plus its very avl... I also put in powerservice white bottle in fuel for anti gel.car runs fantastic,getting me 48 mpg untill last weeks deep freeze,now i got 37mpg. No engine noise just a rattle at idle that goes away when i depress clutch. Starting right up at 8f was lowest so far. It didnt like that it started right up but clanked and clicked for a moment.. Thank you for any ideas.
