Had a 2001 i30 (think Infiniti Maxima) with the VQ30 in it. Sold it to a family member, car has about 110K miles on it and the engine is just about as smooth as day 1. Currently have a 2011 G37 with the VQ37HR....not as quiet or quite as smooth as the VQ30, but a naturally aspirated V6 getting...

Cheapest Ive found is to get the 6 pack at Amazon with subscribe and save. 6 pack comes out to 45, then the 12.00 rebate makes it 33. So a little over 5 bux a quart....its not as cheap as regular PUP after rebate, but its close.

Thanks for the replies! I had not realized how far reaching the 0W-40 PUP was (I also get a kick out of the BMW pic with the pour-er clearly covering where the SRT emblem might be ) It seems like they really are putting "the good stuff" in it even at 240ppm, good on them, I guess. Thanks for...

Looking through VOA and UOAs of standard and SRT PUP oil, I noticed a larger amount of moly in the SRT version. Does anyone know what type of moly is in the SRT oil? Judging from the 70-ish ppm in standard PUP, I would suffice a guess that its tri-nuclear type. But with the SRT oil having ~240...

Originally Posted By: Hammehead Is it the polyolester, not he moly, that quiets the Hemy tick down? My (non-professional) theory is that the oil pressure at idle is too low for these engines once the oil is warmed up. Today, on a not-really-hot day (69 degrees) after 15 minutes of driving I...

Who says its not readily available!!!??

Sorry to resurrect an old thread but it seems relevant: Is the consensus that the Mopar MaxPro in this test is just re-labelled PYB? The numbers seem close but the last time PQIA tested PYB was in 2016. Thanks. -Chris

New '17 Ram owner here...still on factory fill at 1064 miles, have had the truck 2 months. OLM is tracking for about 7K mile OCI (14% used at about 1000 miles). Im not sure how the OLM works in this truck, but it definitely doesn't seem mileage or time based. I started a thread about when I...

I have a Ram 1500 with the 5.7L hemi that "requires" the Chrysler certified oil. I plan on doing most of my own oil changes and I already have a few purchases of the exact spec oil Chrysler *expects* to be in the engine (5W-20, PP or PUP). Im a fan of Pennzoil stuff anyway, but do agree the...

I have a 2011 G37 (sedan) with a whopping 25K miles on it, so I feel you! Ive been using Pennzoil Ultra 5W-30 with a Fram ULTRA filter and I change it twice a year. Im almost positive I could stretch it to once a year, but I prefer to have fresh stuff in place for the extremes (summer and...

2011 Infiniti G37x Out: Pennzoil Ultra (pre-GTL) 5W-30, Fram Ultra filter In: Pennzoil Ultra (pre-GTL) 5W-30, Fram Ultra filter

PUP was out of stock for a while on walmart.com but came back in stock sometime this week. But yeah, in my area (southwest CT) Ive only seen it on a shelf at Pep Boys. Not as cheap as Walmart (34.00 vs 25.00) but if I needed it immediately I could get it. I dont remember having this much...

Just an FYI I feel like I hit the lotto and was able to order a whopping 1 jug of PUP 5W-30 from Walmart.com this morning. Honestly if its this hard to obtain, I might as well just buy Amsoil or Redline, or if I want off the shelf anything NOT Shell/Pennzoil just out of principle.

Originally Posted By: Panzerman Actually they did design different engines in the 5.7 and 6.4. the engines they put in the 2500/3500 are lower HP but higher torque, no MDS and supposedly built for longer longevity. That I did NOT know...if its true, 5W-20 it will be, I guess! Castrol Edge...

Originally Posted By: anndel Use what the owner's manual specifies. If 5W-20 then stick with that as your engine was designed around that grade of oil. Any brand on the Wally Mart shelves would do. The sticking point is that the same engine is spec-ed for 5w-30 depending on what vehicle its...
