Hello all,
My engine builder instructed me to purchase Valvoline VR1 10w-40 now that the engine is broken in. Problem is I can't find this exact type of oil in the USA. It is sold in Australia and New Zealand.
The engine has a flat tappet and 13:1 compression. I was told high zinc oil is best. Can any of you recommend the next closest thing to Valvoline VR1 10w-40? Unless you can help me locate this oil in the USA.
Other information that may be helpful:
440 stroked to 496
I live where the elevation is +/- 100'
The summers days are typically mid 90's, sometimes 105
Thank you all.
