I have a question. I did search but did not see any similar topic asked before, so apologies if it did.
Does the same spec oil with different API have an impact on the engine? 2 different brand of 20W-50 mineral oil but one with API of SJ and the other is SG which is obselete. If i use the one with SG, will it have any negative effect on the engine?
Thanks.
