Spectro R.HDP25 Heavy Duty Platinum Full Synthetic 20w50, 1 Quart

I've used Spectro since the 70's. Engine teardown was always....NO WEAR! I use today and will tomorrow.

It’s all I use

I've been using Spectro in my 08 Road King for the last four years and have been impressed with its performance. I routinely run this oil for 5000 miles between changes and it never shows any signs of breaking down nor does the old oil contain any particulate matter, such as metal. I average five oil changes per year and have my oil analyzed atleast once per year, sometimes twice if the weather has been extremely hot, and have never had an abnormal reading or report. I trust this oil and will continue using it as long as I can get it. My only complaint is I have a hard time finding it locally and usually have to order it online, not a big deal, I just order enough for a couple of changes at a time so I always have it on hand.

Spectro oil is the best. My Triumph motorcycle has had nothing but Spectro synthetic oil since I bought it. I will use nothing else !

I replaced the Amsoil in my 2008 Harley Davidson Roadking With this Product and couldn't be Happier!!!! The bike runs Cooler and Much Quieter!! This is the 2nd vehicle that I have tried Amsoil in and will never again!!!!

Exactly what I asked for

I have been using this oil in my Harley Evo engine from the very first oil change. Quality oil and I would recommend it to anyone that rides their bike hard, I have had no issues with oil breakdown or wear on the motor.

It's my first time owning a Vtwin so im not quite sure yet. Spectro had been great in the past for me using it in inline 4's.Would use this seller again, my order came a bit sooner than promised.
