Sent them an email, no response yet.

Never mind, just found it, Virgin Oil Analyses.

Ah, what does VOA mean?? V??? Oil Analysis

Bought a 55G drum of AMSOIL 15W40 Heavy Duty Diesel and Marine oil in 2008. Used about half but then sold my diesel. Oil has been in my basement which is pretty constant temperature and humidity since then. A friend wants to buy it, but is concerned that it may not be any good. I have no clue...

Since DI diesels need clean fuel, and the new Ford Ecoboost DI engine may also need refined fuel, would it be feasible to use a diesel fuel filter in a gas engine to replace the OEM fuel filter? Would the media melt, dissolve?

I used Penzoil 5W-30 regular oil in 91 Chevy PU for 247K miles before I sold it with zero engine problems, no leaks, and believe truck is still being used in tree cutting work.

Porkchoop, what dino oil do you use in your Harley?

OK already, I changed the oil after only 1300 miles on AMSOIL synthetic along with a new filter. I hope this fixes my problem but I hope the Blackstone Labs test kit arrives soon so I will know the status of my engine.

You may not understand what my concern is. I think I damaged my engine. Nobody has offered me any evidence that I did not so by having my oil checked, I will determine whether my engine is toast or not. I would normally change my oil but by doing this test, I will know whether I should take the...

Are you sure the Delo 400 comes in synthetic? I have never seen it anywhere. I have seen the Shell synthetic but not in 15W-40, only 5W-40. Have you checked their website?

Thanks and I believe I am also obsessive, so here is what I plan to do. I bought a pump yesterday from Autozone, and ordered a oil test kit from Blackstone Labs. I plan to ride around town to mix up my oil and then suck some oil out of the crankcase and send into the lab for a analysis. If it...

Bought a 55 G drum of the synthetic oil in 2008. It is laying on its side on a stand, and I take 5 qts out every 3-4 months. I have a valve installed and crack open the top to vent it and drain out what I need. After searching the shelf life issue, I am starting to worry that maybe I should be...

I usually use Exxon high test, but was running late so ended up at the WaWa and it has 10% ethenal I believe. Then stopped at a Sunoco and filled up with their high test but with ethenal also. As I tried to move from stop to parade speeds, it would ping so I feathered the engine so as not to...

Rode my 09 Harley Ultraclassic in 95 degree stop/go traffic. Engine started pinging real bad. May have been bad gas or maybe engine just got too hot. Using AMSOIL 20W-50 Motorcycle oil in engine with about 1500 miles on the oil and 8500 miles on the engine. Should I change the oil after the...

Just bought an 06 Deuce with 153 miles on it, but one year old. So thought I should change the oil. AMSOIL 20-50 or Mobil 1 20-50 is the first issue. The book says to use diesel oil with API rating of CF-4, CG-4, CH-4 or CI-4, but the AMSOIL and Mobil 1 don't meet that spec. Amsoil has SG...
