I recently changed my oil and went with a new K and N filter. I know a lot use the genuine Toyota filters but I haven’t had any issues with aftermarket filters. What happens is that when I start my can, it seems like oil isn’t getting to the cylinders fast enough, it’s a little bit of a rumble and the light stays on for a couple seconds until the oil is through the system. Could the oil pump be serendipitously going out at the same time I changed the oil? Once the light goes off, it stays off. I live in California, temps at 60s -80s now and I’m using 10w-30 Castro’s full synthetic which I’ve used the whole time I’ve had the van. Any other information I can supply to get help? I’m worried the slightly rough starts will hurt the engine. The engine purrs after the first two seconds and then stays well within proper temperatures while driving.
