July 2, 200520 yr I looked for old posts but couldn't get anything to come up??? (seen tons on this topic but system wouldn't search?) any way. Lets not make this a long discussion: Simply; 84 Brat, EA-81, 180K miles, Carbed, non-turbo. Coming into summer heat, 100+ degrees, regular teenage driver, 10-40 chevron O.K. to use, book (owners manual) shows 10-40, or 20-50. what ever brand.

Slightly longer answer, tight engine, light duty, 10-40 OK. BUT, if the engine smokes a little or will be towing or doing other hard duties - 10-50 might give you an edge. Oh, never think an older engine doesn't deserve regular oil changes - even one that may burn some oil. Any indication that rings are worn/bad will also mean combustion products AND raw fuel are blowing by into the crankcase. So changing the oil will help remove those and keep the viscosity up. my $.02 Carl

July 4, 200520 yr Ok, my question is mineral, semi synthetic or synthetic. Which is best for the ea82? I want to put some 10w40 semi synthetic in mine... is this ok?

Been out of town switching motors in a New 2 Me Wagon. Later,
