Review on Maximize Engine Life with Royal 🔧 Purple 10-454 Extended Life Premium Oil Filter by John Barnett

I can feel a big difference in speed changes around the track, of course I've put Royal Purple 10w-40 oil in my engine and it feels great, without the aggressive speed change the rattle in the gearbox with the force my engine is putting out and apply these settings at 180 km/h (112 mph) and a low speed of 40 km/h (25 mph) and my L98 engine is much more responsive.
