PENNZOIL › Engine oil

Engine noise:

I've been alternating between the OE Castrol (with the free maintenance) and Pennzoil Ultra Euro 5W-40 (502 compliant and recognized/certified by Audi/VW) in 5,000 mile intervals. I've had both tested, and the TBN is higher on the Pennzoil and the viscosity always perfect (Castrol tends to read thinner than 5w-40 on the samples I've sent in for analysis).

Pros: high TBN, perfect viscosity

Cons: Castrol reads thinner

Vehicle: Volkswagen Jetta

In my gen 3, I've used Castrol OE Professional 5w40 (the Castrol in the gold bottle that the dealer sells - oil has a green tint to it), both when I did the 5k mile change and when the dealer did the 10k change.

Pros: meets VW spec

Mileage: 8047 km

i had previously been using Total Energy 9000 5-40 and had been running it for 2 seasons .i would change out the filter after 1 year and top it up with approx. 3/4 qt of fresh oil. i don't drive a whole lot and had only put on about 9,500 miles in that time. i just switched back to Castrol Edge 5-40 this week.

If you're looking for high moly content, I like Redline oil. Google it, there's tons to read on Bob is the Oil Guy alone. That, as well as Motul, have been great in my 2.0T which is pretty hard on oil.

Pros: high moly content

IDEMITSU › Engine oil

You don't need to add any more additives to modern day oils. You said you will be using Mazda 0W-20 oil? This is one of the best 0W-20 oils on the market. It is made by Idemitsu for Mazda. It has very high Viscosity Index of 221. Most 0W-20 oils are around 170. This means it is one of the lightest 0W-20 at start up. This is what you want in the winter.

Pros: high Viscosity Index

Vehicle: Mazda
