Synthetic or Dino?

Syn for the win!

I figure companies spend millions of dollars designing and engineering their product. They install a premium motor oil in the product. So why people send $20 and think it is better than what factory recommends. I just don't understand.

Someone should ask the question, of all the combustible engines ever built on planet earth, how many have failed or had drastic shorter lifespans due to oil preference. I'm gonna go out on a limb and say not enough to ever worry about it.

Certainly agree with your point, changing oil and filter most important. In mid 80s I had 77 corvette whose owner had always used cheap Pennzoil during the time when many said it was worse oil
I tire engine down for rebuild as I wanted more power and that engine with 160k miles was very clean inside.

Being that the oil filter and rear shaft lube are so easy to change, experiment a little to see which one you like best. I bought a case of Honda Full Synthetic 10-30 and K&N motorcycle oil filters. Using them now until gone. Not to sure about 10-30 down in sunny Florida. Will change to Full Synthetic 10-40 by Mobil 1 for motorcycles or Valvoline 10-40 for motorcycles as it is readily available at Wally World. Filter wise, I would stick with the OEM Honda, K&N or HiFlow. And yes, there is a difference in motorcycle oil filters from automotive oil filters. Fortunately it really doesn’t matter as the GL1800 only revs to 6k rpm.

My Valk had nothing but synthetic for the last 117,000 out of the 123,000 that were on her when she went to the new owner. As far as could be told when adjusting the valves there was no sludge buildup in that motor, none. I changed that oil every 5000 miles, not every 3000 like I would have with dino oil, and under the valve covers she looked clean and new.

She ran like new too, in spite of me riding that bike like I stole it for the entire 117,000 miles I put on the clock. Maybe it would have been the same with dino oil, maybe not. But, I would never risk my " B", which I intend to ride the same way or harder for the next 20 years by trying dino oil to find out.

I have read through these discussions before and the only thing I came up with is,,,,
If it feels good, Do It!

AMSOIL you can double your mileage between changes, as per AMSOIL tech dept. Been using it in everything I own since back in the 1980's, never had a oil related issue.

oil threads are great!

WOW!! This is the first oil thread I seen where nobody got insulted. Give it up for individual choice.
