Anything cheaper than GC?

Before dismissing RTS, can you give some hard evidence that they have reduced "the good stuff" which I assume you mean to be ZDDP?

I've looked at VOAs for both CI-4+ & CJ-4 formulations here and on TDIClub; what I've found on average, is this:
CI-4+ RTS: Zn 1403 / P 1249
CJ-4 RTS: Zn 1365 / P 1215

Looks about the same to me - those are easily within 10%.

Is there something else in there which constitutes "the good stuff" that I'm missing? Please enlighten me.

Which 50x.xx rating does WV specify for the car?

In the Mobile Universe...

If you're looking for an xW-30W oil, M1 10w30HM is a close analogue of GC. It's a bit thicker at 40c, but that won't matter one whit in So.Cal. HTHS visc. is identical at 3.6.

M1 0W-40 is fractionally thicker (HTHS 3.7) than either, but it will probably shear more as it ages.

10W-40HM is thicker (HTHS 4.06) than any of the above, and may be closer to the spirit of the car's 5W-40 recommendation.

Wally World sells 5 qt, containers of M1 for $22, and they carry the two HM oils at most stores. (XOM refuses to sell 0W40 in the 5L containers.) Unfortunately, M1's $10 'Ike' rebate program has ended, but $4.40 a qt. is still a solid improvement over the $8 GC you were using. Keep an eye out for upcoming Autozone 'Oil change specials,' you may be able to find GC at a similar price.

Well, the manual says use 5w-40 or 5w30 if you can't find 40.
I didn't bother with the VW specs because I'm out of warranty.

and for the Fram filter, I checked out the Purolator and compared to the Fram. Looked similar and I hear Fram doesn't actually make cartridge filters, I forget who does.

I've had Lubromoly 5w30 before the M1 5w30 and it ran pretty well.

They should look similar. The manufacture of the Fram is farmed out to Mann+Hummel, while Purolator is jointly owned by Mann+Hummel and Bosch. Hmm, similar? I'd say more like identical...
