Re: {Chrysler 300} New Valvoline Product

Very practical, common sense advice that should serve any engine well.

I understand from many pointy headed folks in the Corvette world that zinc, while absolutely critical at first start/camshaft break in is less so for used engines with broken-in camshaft and lifters. These fellas say use Rotella 15-40 in any vintage run-in Corvette engine and advise against the oils without the API Certification Mark. Most boutique oils don't have the API certification. For the Corvette guys using it is tantamount to drinking unpasteurized milk.

I use Brad Penn anyway, have for 20 years. Its consistent with what my engine builder told me. Use a quality oil, pick a viscosity, keep it clean and stick with it.

The most important thing for oil in occasionally used hobby cars is to keep good quality oil clean. Keep the choke properly adjusted. Don't allow it to run eye-wateringly pig rich.

Don't start the engine at all, unless you intend to drive the car 20 or more miles, enough to get oil and coolant temperatures close and boil the water and fuel from the oil, that is where sludge comes from.

Change the oil and filter. Use 1 Qt marvel mystery in place of 1 new qt you are putting back in. Drive the vehicle a few hundred miles, and do another oil and filter change. Stuff is Amazing!!

Hi Kurt,
I’ve been using VR-1 for some time, but have switched. Now I use Driven brand hot rod oil, which is also high zinc, but is supposed to have better longevity. Sometimes you see VR-1 on sale at Napa. If you are trying to run oil for a short time then change it, VR-1 is cheaper on sale and should be just fine…

i had a 59 rambler given to me free , 100 k, in college , I was broke

oil filter was optional on 59 rambler ( cross country wagon) this one did not have one (!) Also experimental aluminum block , caused other issues , anti freeze / clogged radiator, pia

Guy had been putting used oil from friend’s gas station in it ,100 mikes a quart .

Drove it home decided oil change might help , removed plug nothing came out (!)

Turned out 1.5 “ solid sludge in oilpan was blocking the drain

Oil pressure ok . (!) anyway

put big screwdriver through sludge black goo came out . On my own decided flush w kerosene , not driven , just idle , Did that three times used coat hanger wire bent to L to kind of stir things up .

put in good oil , drove it at 80 , maybe 500 miles ran better and better . Changed again still black , But ended up 3 years with it maybe 50 k more miles , stopped burning oil too . (1 per thousand)

Drove sadly into junk yard running great , 150 k, body rusted out . The front seat turned into a bed . Awwright

Went on honeymoon in it !

I would not worry about clogging screen , and modern oil filter will grab any small stuff . Do it , change filter and oil 2-3 x .Maybe 500-1000 miles apart Drive it hard and fast , nothing to lose

Gunk is really a very fine particulate deposit , wont clog anything just moves to oil filter ?? remember , seeing gunk deposit in valve covers is not about what is inside engine , like bearings. Looks bad , might not be causing any problems at all Old machines get dirty ; oil pressure is the thing to watch

I would be afraid that all that loosened sludge would eventually make it to the oil pan and clog up the pickup screen.

Does anyone have experience with the Valvoline “Restore and Protect” product?

https://shop.valvolineglobal.com/products/restore-protect-full-synthetic-motor-oil-sae-5w-30

Sounds tantalizing, as do long-term effects, but I’d like to know if the claims are real. My ‘64 Imperial was owned by a spinster who lived to 105 (imagine driving with gloves/hat at 40% of posted speed limit) and there was considerable sludge on top of the heads when I pulled the valve covers during a seal and painting excursion a few years ago. I cleaned what I could but fear more exists elsewhere.

This Valvoline product sounds like it would be a good solution, perhaps there are others as well?

Appreciate feedback in advance!

Thanks,

Kurt
