Guest Rob J Posted July 9, 2011 Share Posted July 9, 2011 Just curious as to what viscosity oil you guys are using in your 401-425 Nailhead engines?I just picked up an 88k mile 65 that hasn't ever been rebuilt.Any of you guys using a ZDDP additive to your nailheads? I wonder if it is really necessary.Rob Link to comment Share on other sites More sharing options...

60FlatTop Posted July 9, 2011 Share Posted July 9, 2011 I usually buy Texaco oil for all the cars. I was raised in the 1950's and buying Texaco gives me the image of an American Indian riding off into an oil field sunset; head dress, Buick convertible, and all. Maybe a Caddy, but nothing less.It may be a fantasy but it sure makes me feel good. I would love to see them get my oil money.Bernie Link to comment Share on other sites More sharing options...
RivNut Posted July 9, 2011 Share Posted July 9, 2011 No matter what brand you buy, unless it's something that's been on the shelf for 25 years, you're not going to find an oil that's designed for flat tappet engines. Overhead cams do not require the same type oil that the older engines do; the only thing close is over the road diesel engines. At the ROA event in Branson last week this same topic was brought up. This is what was said. "Look at what the NASCAR guys are using" Theirs are the only modern engines still running flat tappet cams that need the ZDDP. The gentleman that was relating this to us said that a chemical engineer that he met recommended that he use the oil that Joe Gibbs had developed for his race car engines.

Jim Cannon Posted July 10, 2011 Share Posted July 10, 2011 I use 10W40 "high mileage" non-synthetic oil in my '63 with about 96 k miles on it. It has never been rebuilt. I change it every 3 k miles or 1 year, whichever comes first. It has enough ZDDP. Not really high levels, but enough. Link to comment Share on other sites More sharing options...
lrlforfun Posted July 10, 2011 Share Posted July 10, 2011 OK Riviera people: I usually get what Wal-Mart has, a 10-40 or so. I ALWAYS add a quart of Marvel's Mystery Oil and a fresh filter as part of each oil change. This being said now.............HERE'S THE MOST IMPORTANT THING TO CONSIDER, because these cars are old and they sit for long periods of time with out being started. They have carburetors and in order to start most of these cars you have to pump the living daylights out of the gas. Result? A crankcase that has lots of gasoline which can easily kill the engine. The solution? Start your car as often as possible, let it warm up to operating temperature and always always always check the oil and make sure it's clean clean. For some reason the 425's are lousy and the 364 and 401's seem to hold up much better especially now that they are so old, have been out of daily service for a long time and are laying dormant. This is just my experience. Mitch Link to comment Share on other sites More sharing options...
60FlatTop Posted July 10, 2011 Share Posted July 10, 2011 Don't let them sit. Strive for 15 miles per week minimum. This will also maintain your car at its highest value.Cars that don't get used don't need to- stop well, cool well, start well, steer well, and on and on.This leads to deferred maintenance (benevolent neglect) and all those things are repair jobs the new buyer deducts from the value should you decide to sell.Splashing hot oil inside engines, transmission , and rear ends is just the greatest thing you can do for your car!

Jim Cannon Posted July 10, 2011 Share Posted July 10, 2011 I agree that fuel in the oil is a big drawback on these older cars.It is good to drive them often. BUT, a bunch of short trips is actually worse than not driving them at all. You need to get the engine and oil quite hot and keep it hot to drive off the fuel and the water vapor in the oil. This is really hard to do in the winter. If I drive the Riv, I try to drive it at least 20-30 minutes minutes, not shorter trips than that.

This is just my experience. Mitch Mitch, do you put the one quart of Marvel Mystery oil in place of one quart of your regular oil? By example, your engine calls for 4 quarts of oil with a new filter. In this case you would put in 3 quarts of your regular oil and one quart of Marvels Mustery oil. thank you Turbinator Link to comment Share on other sites More sharing options...
lrlforfun Posted January 13, 2019 Share Posted January 13, 2019 OK Bob: I put in 4 quarts with the fresh filter and let it warm up. Then I check the oil and usually top it off with the quart of Marvels. The Marvels, fresh oil and driving these things as often as possible is the best recipe to keep 'em up. Don't forget that carb too because now the gas tanks are dropping like flies and that contamination eventually gets to the needle-n-seat allowing lotsa gas to get into the crankcase which is disastrous.

offdensen Posted January 14, 2019 Share Posted January 14, 2019 (edited) I also use the VR1. I can only imagine that it bodes well with my engine. It's quiet, idles fine, but I also change my oil pretty often since I work at a shop and have the basic knowledge and means to do it myself, which helps keep the cost of oil changes down. I prime my oil filter with Marvel Mystery oil, and change the filter every other oil change. I think I might be overkilling it, but I do drive it quite often. The oil stays that amber color for awhile. When I first got the car the oil would blacken immediately after use and this annoyed me so I decided to start changing oil more often and now its stays a good color for a while. At this point I change the oil 2-3 times a year depending on usage Edited January 15, 2019 by offdensen (see edit history) Link to comment Share on other sites More sharing options...

Mitch Mitch, thanks. Understood. I start the car often in the Winter and let idle for 10-20 minutes. Too much salt on the roads after snow fall. Even if the roads are dry it takes some rain to wash the salt off the road. I undercoated per exact directions with POR 15. I missed spots inside the metal frame supports. I have a plan to get the insides as well. Thanks again for the tip on 4 quarts, new GOOD FILTER, and top off with Marvel. I use only ethanol free gasoline.

I’m too big, too arthritic, and starting to age a bit for to crawl under the car, but I can if necessary. Turbinator Link to comment Share on other sites More sharing options...

RivNut Posted January 15, 2019 Share Posted January 15, 2019 Johnrex let me know about the Mobil 1 Synthetics a few years ago, after he'd returned from the SEMA exhibits and sat in on a discussion of oils for older engines with flat tappet cam shafts (like you have in your nailhead). I've been a user ever since. That coupled with a Wix filter and I feel safe under any driving conditions. (Wix also makes the NAPA Gold filters). Here's a blurb that I found on a Q&A part of the Mobil 1 website. I buy the high mileage 10W40 myself. Wally World sells it for between $25 and $30 depending on what's on sale at the time. No shipping, no waiting. Q: “For an older, flat tappet, performance motor with inherent cam wear issues is there any benefit to mixing high ZDDP Mobil 1 Racing™ 4T 10W-40 to Mobil 1™ High Mileage 0W-30 oil? The 15W-50 creates TOO MUCH oil pressure. It would be nice if you had a product for 'Classic' cars, high ZDDP, 0W-30 and 0W-40. I have used nothing but Mobil 1™ for 15+ years.” A: Mobil 1™ FS 0W-40 already contains a higher level of ZDDP (1,000 ppm) that could benefit your flat tappet engine. We also have a Mobil 1™ High Mileage 10W-40 (1,000 ppm); see our table listing the phosphorous levels for all Mobil 1™ synthetic motor oils.

I have seen the Joe Gibbs product in action. I validate its cost in a classic car by how often I actually have to change the oil. Once a year if that. 1 Link to comment Share on other sites More sharing options...

RivNut Posted January 16, 2019 Share Posted January 16, 2019 (edited) There are a lot of considerations beside "What the other guy is using." How many miles on your engine? Has it been rebuilt? Have I owned the car since new and used the same oil? What kind of oil did the original owner use? How hot does my car run? How much do I drive it? How often do I run it at max rpm's for long periods of time? When's the last time the bearings were inspected for discoloration or wear? When did you last mic the crank and rod journals. What is the ambient air temperature in the garage (or outside) when you first start the car? A lot of you mention the oils that you use, but do you actually know the ZZDP and Phosphate levels of those oils or are you just saying they're good because your engine is still running? Have you talked to a tech rep at the producer? If your engine has 120,000 miles on it and it runs hot, should you be using the same oil that an engine that has only 60,000 miles on it and runs at proper temperatures? Lots of things to consider. There are a lot of articles to read and info to be digested before deciding on what's right for you and not for the other guy. One of the latest articles that I read says that Shell Rotella Diesel oil is really good and not that expensive and not to let the word "diesel" mislead you. A friend of mine who manages and Advance Auto Store told me a couple of years ago that he sells Rotella to a customer for his old Jeep Cherokee with the in-line 4.0 liter six. It's used as a rural mail delivery vehicle and it had 450,000 miles on it at that time. Never been overhauled; just regular oil changes using Rotella.

RivNut Posted February 4, 2019 Share Posted February 4, 2019 I just read the info on the 10W-30 and 10W-40 Lucas oils. It states it has "high" levels of zinc, molybdemun, and phosphate. The last sentence in the second paragraph says "not to be used in passenger cars" but says it's good for muscle cars, classics, and hot rods. Which is it?

jsgun Posted February 4, 2019 Share Posted February 4, 2019 I'm going to use royal purple break-in oil. Motor only has about 200 miles on it. My understanding is breakin oil has lots of zinc. After about 1200 miles, probably switching to their synthetic. Been running it in my GF's Rav4 since it was new, it's up to 280k miles and no smoke or rattles. Seems to do ok.

Biggest difference there is that your Rav4 has a roller cam in it and there's no real wear on a roller cam compared to a flat tappet cam. Just make sure the zinc etc. in your daily oil has the needed zinc and phosphate levels. What works on modern engines ain't good for older engines.
