Amsoil has change oil recommendation for Viggen ?? Posted by Jake [Email] ![]() ![]() |
I have been using Amsoil engine oil for about 10years on all my Viggens and 9-5 Aeros.
Recntly Amsoil has change their recommended oil from 5W-40 synthetic European fomular to synthetic 10W-30 due to the oil sludge problem. I never had a problem with sludge and not sure if I should go with the recommended 10W-30 or stick with 5W-40...especially in the summer months.
Any feedback?
