Getting read to change oil on a 1985 Nissan Pickup (2.4, automatic) with 99K miles. I have some conventional Pennzoil High Mileage 10w-30 that has been sitting in the garage for around 3 years or so. I was going to use that and a Fram Tough Guard (what Walmart had).
Googling around the internet I see some people saying that an older flat tappet engine like this should have an oil higher in ZDDP. And, there's no better place on the internet than here to ask an oil-related questions.
Is the Pennzoil High Mileage 10w-30 fine? I definitely want to keep the truck for many years, so if it's not I'd certainly be willing to go buy something else.
And, out of curiosity, oil sitting for 3 years in a bottle should still be good, right?
Thanks.
