More and more I find myself having to speed up to keep up with modern cars. My 1991 Toyota Previa is geared way too low for my comfort. 5th gear is around 3700rpms at 70mph. I’m nearing 4000rpms at 75mph. Do you guys think my concern about this vehicle’s longevity is unfounded? I just have this paranoia that the engine is going to blow up or become a big oil burner running those rpms for so long on the freeway. I put red line oil in it to appease my paranoia. Do you guys think this engine can last for a long time? The engine is a jdm engine with unknown miles, but was in spotless condition when installed. Been running it for a year now with no problems. It’s a 2.4 liter 4 cylinder. I know modern cars like the Honda Fit spin fast also, but those are smaller 1.6 and 1.8 engines. I think smaller engines would work better for those rpms
