Purchased the smokeless 10w30 through another channel but it shipped from FHS. I didn't have a bad smoke issue it only occurs if car is revved hard with no load. I drained the oil and installed a new filter before pouring in fhs smokeless. After first start and letting it warm up no smoke not even under high revving and passed state inspection.

Haven’t got to use it in my open motor yet but back in the day i ran it in my limited modified flat head Briggs worked great.

Great product

If you're wondering, this Smokeless oil works!!!! NO SMOKE!!!!!

I bought my 2008 Dodge Dakota brand new, I've always changed the oil timely, but lately, only occasionally, smoking a bit -- anyway, the first smog test place guy told me my engine is "worn out", I bought your smokeless oil, and behold no smoke of any kind, this past Saturday I went to another smog testing place, truck passed with flying colors!
