My Real-World Test with Synthetic Oil

[Realmongo]

After I broke in the engine on my new Silverado 4x4 and commuting through rural driving, I got a steady 16.7 MPG out of it. When I switched over to Mobil 1, that number increased to a steady 17.3 MPG. Has anyone done a comparrison with 1/4 mile runs?

I did it on a dyno between Royal Purple and Valvoline VR1. The VR1 made 8hp more.

edit: it may of been 6 was two years ago.

Did multiple pulls on the VR1 and was staying within 1hp each pull. Swapped to RP and warmed stuff back up, made a few pulls and the closest it ever got to the VR1 was the 6-8hp down.

Well that does show a little free HP. Maybe I will give it a try with my girlfriend's Sable next spring.

I have had 2 different vehicles that I bought new, drove 5k miles, switched to Mobil1 and gained 30-40 miles per tank. It is more expensive than conventional oil, but more than pays for it's self in fuel savings. I put 200k miles on both and neither needed oil added between changes at 10k miles. I use Mobil1 in everything I own.

Except my findings were opposite. LOL VR1 is non synthetic and made more power.

Is the VR1 synthetic blend?

I'm curious since we are talking about oil, if I should keep using the Valvoline Durablend or switch to Mobile 1 in my 65.

Pretty sure VR1 is a conventional oil with extra zinc.

nvm, quick search confirmed it. lol

One of the best synthetics is Amsoil, and a friend of mine is a dealer. He can talk with you about the 1/4 mile times, and it is true not myth.

I am going to replace all of my fluids with Amsoil...one of the oldest synthetic companies...great product. He delivers it straight to your door.

If you need any info, contact me:

Sorry, I'll pass on Amsoil. I don't support MLM schemes. I don't care if its the best stuff ever made. I also won't run stuff that I can't just go pick up at the store.

Has anyone here heard of or had any experience with Schaeffer Manufacturing oils? It was recommended by a local speed shop/circle track parts house. They claim that for a street/strip application, it beats Royal Purple, hands down. They sell both product lines.

Schaeffer Oil 3.0 | Industrial Lubricants | Diesel Fuel Additive | Synthetic Motor Oils

Just Curious,

Synthetic is usually slipperier, and the gains can be both in mileage and 1/4 miles times. Anyone who has tried to use synthetic in a motorcycle with a wet clutch has learned the hard way.

i use mantek s/blend.

I ran automotive Mobil1 in all my bikes. The only thing I saw it that it made them a little grabby. I never had slippage problems though. We ran 2 seasons on a gsxr750 endurance racing with the same clutch. I was ruthless on the clutch at the start of a race too. I usually pushed against the front brake to get the clutch hot so it would not bite too hard. Same thing with my sprint bike too.

That's strange, when the local Harley Dealer sevices my bike, he always uses the HD-branded synthetic lubricants.

 

[brianj5600]

Most Harleys have seperate oil for the engine and the trans/clutch.

I have been looking at Joe Gibbs oil for a while and after talking to one of thier reps at a local round track swap meet, I picked up a case of Joe Gibbs Hot Rod synthetic for my car today. It sounds like a good fit for me.

When I have changed out regular oil the viscosity is much thinner than when I put it in. Mobil 1 seems to be more stable in terms of viscosity. Big deal in a hot climate.

I just put synthetic in my 1 ton duramax diesel pickup, I went from 15-40 to 5-40 synthetic, I did notice my oil pressure slightly dropped at idle, I will be making my usual 260 mile trip to the river tommorrow, we will see, usually at 80-85 mph I get about 17 mpg. I've ran synthetic in the stang for 15 yrs even the new 408 after 800 miles got some of the new castrol super duper synthetic.
