Rather than being long-winded, I'll present my questions in a numerical list to alleviate alot of reading for you. I partial to Pennzoil, but will use other quality oils; my goal is to fully utilize whatever oil I purchase while trying to save myself a dollar in the process.....this could be considered an oxymoron.....

1. I have a 2009 Chevrolet Silverado that sees predominately highway use; very few short trips, oil always comes up to operating temp and is maintained for quite some time. Without spending the money for UOA's, can I get by using PP and a Fram Ultra doing 7500 mi OCI? Perhaps it would be worth the money to run a couple of UOA's and stretch the oil and filter to one year or 10K. The truck is equipped with an OLM, but I prefer to do an OC based on time/mileage.

2. My wife's DD is a Pontiac GP with the Series II 3800 engine. She makes two short trips five days a week to the bus stop; less than two miles each way. In addition to the aforementioned short trips, the car is driven around town 5-6 days per week on 16 mile round trips.

Would PP and a Fram Ultra be capable of doing 7500 mi OC's with such frequent short trips or should I go back to dino? If I do go back to dino, should I do 3000 or 5000mi OCIs?

3. Considering I go back to dino on question No. 2, I'm considering PYB or Havoline in the 5W-30 flavor. I compared the two oils last night on PQIA; both oils appear to be of similar quality, but the Havoline really lacks in Moly compared to PYB. Should this be of concern to me? If not, Havoline would get the nod just due to being a few dollars cheaper.

If you need additional information, please ask.

Thanks.
 
Short answer.. M1 5-30 for 10K OCI in both engines. Any decent oil filter, and skip the UOA, unless you suspect a coolant leak or fuel contamination.
 
I'd follow the OLM in both vehicles using any quality dino in the correct grade. You could probably safely stretch past the OLM a little if using any synthetic. GM spent a lot of time and money coming up with the correct OLM algorithms, using it will be much more accurate than any seat of the pants feeling you have.

Seems the PYB has the bigger following so I'd vote PYB....or MS5K
 
I'm more concerned about the the Moly....or lack thereof in the Havoline.

Someone enlighten me one this one.

I would not pay attention to a single additive in motor oil. I am sure the guys at Chevron know how to formulate a proper lubricant.

There's more to engine oils then what you see on paper.
 
Just use the OLM. The interval it suggests is tailored to your driving conditions. The OLM's suggestion should be fairly constant as long as your driving patterns. So you'd already be changing it based on time or mileage.

Even the cheapest API-rated dino can handle whatever the OLM suggests, but no longer than one year (the latter only being an issue for rarely-driven cars).

That said, PP and Fram Ultra should be perfectly capable of 7500 under the conditions you described.
