I drive a 2003 VW Passat. This is the oil I used when I had my oil changed last. The place I got my oil changed at said it would last for 10,000 miles, but I didn't know whether that was true or not. Any kind of Refference that anybody could find would put me at ease. Thank you.How many miles will Pennzoil Full Synthetic 5w-30 motor oil run without having to change it?it all depends on how hard you drive the car, but 10,000 miles would be the longest i would go, I would get it changed around 7500 if i used a full syntheticHow many miles will Pennzoil Full Synthetic 5w-30 motor oil run without having to change it?I would have it changed around 5,000 for best results.How many miles will Pennzoil Full Synthetic 5w-30 motor oil run without having to change it?You didn't mention what engine you have, but usually VW's need oil that meets one of their own specs such 502.00, 505.00, or 505.01. I don't know about Pennzoil synthetic but something like Amsoil Synthetic 5W-40 Euro Car Formula meets those specs: https://www.amsoil.com/lit/databulletins
An oil meeting VW's standards will enable the car to go the full extended drain interval recommended by VW. Hope this can shed a little light on the subject. If you need more info on Amsoil synthetic oil or extended drain intervals, check out my website/online store:
