Is there something that "clings" well to engine internals over time, up to a year or more?
I have a few cars and motors that sit around in storage for long periods. On one vehicle with a Nissan SR motor, I started using some Amsoil Z-Rod 10W30 a couple years ago. I typically have the motor started up again within 7 months after being in storage over winter. This year I did not get around to it until about 13 months. I ran into issues getting oil pressure on the first start because the oil pump had lost it's prime. Luckily I was cranking with the plugs removed. I tried about 4 times cranking for 10-15 seconds with no luck, this was strange to me because typically in the past I would get pressure within 5 seconds, so I stopped. I removed the oil filter and using a filter bypass adapter block, was able to pour some oil into the filter housing so it could drain down and wet the oil pump gears. That did the trick and my oil pressure was back within 10 seconds of cranking.
Now I know a pre-oiler or accumulator (like an Accusump) would be ideal in my situation. But as for an oil, is there something better I could be using? Heavier/lighter? Especially to protect components during extended crank times with no oil pressure?
