Hi
This is my first post at BITOG, so bear with me
I got an ’65 Impala with a 283 small block, running what I think is the stock flat tappet hydraulic cam. It probably has the original valve train and oil pump.
I don’t fancy dino oil, and I’ve never used it any vehicle I’ve owned.
Up to recently, my oil of choice for my (other) vehicles was a store branded 5W-40 synthetic. (Our equivalent to Walmart’s SuperTech)
VOA of that oil: https://bobistheoilguy.com/forums/attach...97_page_002.jpg (grey column to the right is the VOA)
I changed over to M1 0W-40 a while ago since it’s now possible to import it for a reasonable price. (Fun fact: a quart of M1 0W-40 costs 27$ (US dollars) here if bought over the counter at a regular store. Not taking into consideration the 6.2$/gal fuel price just to get to the store)
I don’t feel confortable running a flat tappet engine on the 0W-40, mostly because it’s API SN-speced. Am I wrong? Can the M1 0W-40 provide the necessary start-up protection, especially if the vehicle has been parked for a month or two?
Even though the Impala isn’t driven at low temperatures, I do need to move occasionally during the winter. It is also frequently started in the spring when the temperature is around 40°F. It is subjected to long periods of idling and cruising at idle rpm. (Long periods as in several hours at a time)
Can I use the M1 0W-40? Should I use another oil more suitable? Valvoline VR1 5W-50? I no longer care about the oil price. I just want the best possible oil for my application.
Some American brands such as Amsoil, Royal Purple, Quaker state and Pennzoil can be quite tricky to find here. But if any of those have what I need/want, I’ll find a way to buy them.
Any thoughts? Am I overthinking this?
