Does anybody know anything about this oil? Is it a group 1 or group 2 basestock ? Does it have higher boron levels like Pennzoil etc..It is readily available at a reasonable price in my local supermarket and it is the weight specified in my wifes Honda. Before finding this sight I was sceptical about 5w20 oil and thought about using 5w30 in summer. Now I will probably use 5w20 year round.
