I found some Vintage 1988 Valvoline all season 10w40 oil on the back of a shelf in the garage. I also discovered some vintage Kendall Dextron 3 from roughly the same time period. Would you use either of these or pitch them?
If it's an old car or old lawnmower then I wouldn't mind using it, otherwise, nope.
Q.
X2. That oil is probably SF or maybe SH. Not approved for new cars past 1994 atleast. I wouldn't use it unless you have an older car specing that oil and even then - today's oil would be better. Lawn mower - fine.
