Calling for opinions, next step concerning oil
OK on my 70 Nova 350 stocker build, I have the new motor in, fired it up with the Gibbs break in oil for 25-30 minutes at 2000 rpms using the low tension valve springs. Changed the filter and replaced the lost break in oil. Any thoughts out there about letting the break in oil stay in it and running it some with the new springs or does the break in oil need to come out now that the initial break in time is done ??? Any opinions on where to go from here ??? Is there a rush to get the break in oil out ???

I use the Valvoline Race Oil 10-30 non synthetic. Lots of zinc. But it doesn't hurt to run the break in oil.

No big rush to get it out that I know of. I've had the best luck with new rings sealing up with that BR30 oil.
I know an engine builder that runs BR30 all the time in his own car, unless he has a tough heads up. |

The gibbs oil .has a lot of paraffin's [wax] if you do not have heat In the motor it gums up the fine microns in the filter. This starves... some places in the engine and causes problems.TOM

Re: Calling for opinions, next step concerning oil
Zero-10wt Royal Purple is the only oil I would run cold. Never tried to run anything else without putting some heat in it. Patterson puts Gibbs (now Driven) oil in his Comp & SS stuff. I use the BR30 (5W30 wt break-in oil) with no problems. If you drain it cold, it leaves a lot of stuff black in your pan. I like to warm it up, or drain it not long after shutting it off. Black stuff is still in suspension. I haven't tested the zero wt Gibb's/Driven oil yet. Alan Patterson says it's good, so I am sure it is. I run my clearances on the right side. Loose engines seem more forgiving to me. Just what I have seen with my junk. Can't afford to have it done, so cobble my junk together myself.

Have you guys ever tried the Brad Penn Green Stuff 10W-30 oil? It has a lot of zinc.

Re: Calling for opinions, next step concerning oil
I was using the XP1 (5w20) all year and had the end result of oil related issues. I know it leaves black stuff in the pan and have seen the wax/paraffin suspended in the bottle. Once you shake it up, it breaks up and goes away.
Anyone tried running Mobil 1 5w20? I assume there would be nothing wrong with running it. |
