Engine oil Shell or RED LINE

My '03 jetta tdi just turned 84000, I have used the rotella synthetic 5-40 the whole time. I change it about every 7,000. I'm in the northeast. Last year it got down to 10 or 15 below quite a few times. It sounds like someone shaking a buckets of marbles when I first start it, but it smothhs right out and allways starts. Rotela is ok by me.

Mobil 1 0w-40 is approved by VW, Porsche, MB. If you don't mind the price, Redline 5w-40 is excellent for our 1.8T engines. From the oil analyses I've seen, Redline has shown a few \"Parts Per Million\" less in metal wear than Mobil 1 5w-30 or 0w-40. Redline has more Moly than most oils. But for me, a few PPM is insignificant over 7k-8k miles. I still use Mobil 1 though cause it's cheaper (Costco) and can be found anywhere.

Lately, I've been using the Rotella Synthetic 0w40 which is available at Canadian Tire. It conforms to the required specifications for the non-PD engines.

Canadian Tire sells Shell Rotella SB full synthetic. Great for our TDI's....

Never tried Royal Purple but have used Redline a few times before and will continue to use it. Great stuff!

Another option is the Shell Rotella T synthetic 5w40. It's not a PAO base stock. But it's $13 a gallon, for cheaper oil changes.

I recently put in Shell Rotella t, 15w 40 and it seems to work a lot better than the castrol 15w 40

Definitly noticed a difference from dino to synth, through research redline seems to be one of the best....so thats what i use

Go with the Shell Rotella 5W-40 available at Wal-Mart

Wear values perfect ! Looks like Redline is lowering the Moly value some . Your nox is normal but new plugs or wires could help lower the values, Oxd is elevated by cleaning effect of the POE base and lab equipment hates Redline, no problems though. Second change on this oil will drop OXD values. As I said before I have not seen this formulation before but it looks ROCK solid. Good TBN retention.
