Engine oil Shell or PENNZOIL

The same oil goes into all GDI engines at my dealer, which is Shell Helix Ultra SP 0W-20. This is a super expensive, latest spec oil. Oil changes with this oil are done at 9320 miles if turbocharged and 18 640 miles if naturally aspirated.

I combine that with Pennzoil Platinum as there’s almost always a rebate for it. I paid $12 a jug after rebates for my last batch.

I have a buddy that used the Shell Rotella diesel oil that is dirt cheap for his 2009 r1.

I personally like using pennzoil euro platinum 5w-40 in my Mk7.

I've run Pennzoil Ultra in 5W-30 for the past 4 years and never had a problem.

I'm at 365,000 km and switched to Shell Rotella T6 probably 30-40k ago. Oil consumption was at last halved - the detergents in that oil really help clean up deposits in the rings, or so I'm told.

Some 5w-40 can be quite thick in cold. The 0w-30 here is German Syntec, and trust me it's the same visc curve as 0w-40. As you see, 5w-40 is 3-4x thicker in cold than jug 5w-30

Quality synthetic oils provide the lowest oil temps, longest running life and superior lubrication. I use Shell Rotella T5 10W-40 for Texas climate.

I use Pennzoil Ultra Platinum 0W-20, and follow a 5K miles/6 months time change schedule. (It’s twice as often as is recommended but that’s just my personal preference on how often I change it, not indicative of oil quality or use parameters.)
