I have a bunch of long trips planned in the next month. Hot weather and mountain driving included. I plan to take my van and its due for an oil change. Up til now I was using PYB and thought why not go full syn. I have Pennzoil Platinum on standby. Would it really cause all kinds of leaks and increase my consumption? Or should I just blend the PYB with PP?
Long hauls = go full synthetic?

Whatever you have on hand.. stop and go traffic is harder on oil than long trips.
What he said. Yu need the advantages of synthetic in stop&go, and for short journeys.
Hours on end at 70-80mph is easy going and a conventional will handle it with ease

How many total miles on the long hauls?
Syn is great for cold flow, for short tripping, and for extending OCIs.
But a good conventional in an engine that doesn't spec synthetic can do fine for around 7500 mile OCIs in a well running engine assuming its no severe load (towing a full trailer at 80 MPH up 10-mile, 8% grades, etc).
So if the total mileage of all your long hauls is 7500 miles or less, Id stick with PYB. If you're looking for other convenience or the need to not change, you may consider syn. However, without baselining it by UOA, you won't know if you can extend much further or not anyway.

Run an oil that meets the manufacturer's requirement/recommendation and run the OLM. Chances are it will run at least 7.5k under the conditions you describe.

+1. Stick with what you are using. How many kms will the trip be?

Long trips you say? Can I come with you?=-=-=-Kira (half my genes must be dog as I love the car)

We're not from a very cold area. It doesn't get much below freezing.
Change the oil now with PYB and maybe change it again after the trip?

Sounds like a plan
