I use it in both my BMWs, and have had no problems. However, I live in SoCal where there is a mild climate. Perhaps a quart or two of a 10w30 would work with the mix.

: Local parts store only had Syntech Blend -Dino with synthetic added, and only in 20w50. I usually use regular Castrol 10/40 or 15/40. Should it be OK to use in southern Virginia? It's an '89 M20 2.5L
