Is it alright to use 4 quarts of 5w-30 and 1 quart of 5w-20 oil in my car? The car is a 2004 Subaru Legacy and the oil is Castrol Syntec Blend. The car only takes 4.7 quarts of oil, so really I'd only be using .7 quarts of the 5w-20. Using two different viscosity motor oils
there will be no problems mixing the oilUsing two different viscosity motor oils
I would switch to full synthetic, but there should be no problem.
