I was wondering which is the better full synthetic oil in 5w-30 and 5w-20 weights.

They are both good oils.

What is your definition of "better"??

Is better...... cheaper? - quieter? - less consuming? - longer OCI? - stays clearer on the dipstick longer? - what?

If it helps your decision any, some guys on the board have commented on how their Pennzoil Platinum has had a burnt smell coming from it.

When cold, valvoline syn in our 2.3L accord was the noisiest (valvetrain) oil I ever experienced, even over dino. Never went back, tho valv. is still one of my favorites

best for longer oci, offers better engine protection, has a better base stock and add. pack.

Both these oils, in the lower grades (30 wt and below) are girly-man oils (based on the criteria of "Energy Conserving" and starburst certification being weakening agents that result in lower HTHS among other things). You need to try some manly oil like Maxlife Synthetic or the new Mobil 1 High Mileage.

I've run both in my Volvo turbos. The SynPower was consumed at a much higher rate than the PP. Of course, both of these cars have well over 150K on them, but have never exhibited any consumption issues on a variety of other oils including Shell Rotella T syn, Chevron Delo conventional, GC, Castrol Syntec blend and Motorcraft blend. Just on SynPower.

I will run these in 2 Nissan VQ series engines (2004 Infiniti G35 w/ 3.5L V6 and 1999 Nissan Maxima w/ 3.0L V6) and one Honda 3.5L V6 that's in a 2006 Honda Pilot. None of these cars have consumption issues. The VQ35 is currently running on PP. I am waiting to convert the Maxima to full synthetic after my 2nd rinse phase of Auto-RX ends, which will be in 200 miles and waiting until the Pilot hits 10k to convert it to a full synthetic as well.

Synpower, and many Group III oils have poor Noack volatility which may or may not contribute to oil consumption. On the Grill, Synpower evaporated extremely fast. Knowing Valvoline, they probably are not using that high quality of a base oil. IMO.

VQs seem to like a thicker 30wt oil - Tall Paul's Maxlife Synthetic suggestion is a very good one for these engines. The ML syn is ACEA A3 rated, and can be found for $1/qt after rebate right now (rebate forms are at Pep Boys, but can be used anywhere as they are paid by Valvoline).

The Maxlife that is on sale at Pep Boys is a Synthetic Blend? The SynPower is the full synthetic they have on sale. Is it not?
