@@glengillham4629 - very true. Also, since every major engine now has roller cam follower or lifters, they've reduced the zinc content (for good reasons) but it there are other areas that have suffered for lack of startup lubrication. Areas of peak sideloading in the cylinder, especially.

Good analysis and now I understand better the reason some of today's motor oils have been reformulated. I recently quit using Mobil 1 in my C4 ZR-1, based on a recommendation from the C4 ZR-1 guru, Marc Haibeck from Haibeck Automotive in Addison Illinois. The LT-5 dual overhead cam engine originally recommended the use of Mobil 1 and it came from the factory filled with it. All 11 quarts. According to Marc, the zinc phosphorus content of a motor oil used in this engine is critical to minimize cam wear. Mobil 1 reformulated their traditional oils and decreased these respective contents of zinc and phosphorus over the years compared to their original oil recommended by Chevrolet. I did not understand the "why" until I saw this video. I have switched to AMSOIL which has a higher content of zinc and phosphorus compared to the current reformulated Mobil 1 products. I have used Mobil 1 products in all of my "normal" cars since the late 80's. I have had hundreds and hundreds of thousands of miles driven with never an oil related issue. I was not aware Mobil 1 had a Racing Oil that would meet the needs of my ZR-1 once again. I will run this video past the C4 ZR-1 community for their feedback. As always a great video and thanks.

[@MassiveTrackHunter]

So the answer is yes you can, in the summer, since it will flow like crap in cold weather, BUT... if the zinc content is higher in the race oil, it will foul your cats faster. If you expect 200k miles out of your cats, it may not be a good idea to use race oil, but then again if you drive it like you need race oil....you won't hit 200k cheaply anyways, if you even make it there.

I just sold my old Tahoe, that has 300,000 miles on it. The only reason it lasted that long is regular maintenance. I changed parts as they wore out. Didn’t have to do much to the motor.

[@sebischmitz777]

YES it's okay to use Racing Oil. IF you know what you're doing. Reserach the TBN and base the intervals on that. Racing oils usually have a TBN similar to regular Oils, so there's nothing to worry about. Also, look at the additives present. If it's a modern formula with Molybdenum and Boron or even organic friction modifiers then don't put it in your 40 year old Muscle Car. If you don't understand it, don't use it.

Standard grade oil should be fine for most all applications in consumer cars. I bought a $10k Escort in 94 and planned to drive it for many years. I started using a synthetic oil. At just 50k miles someone t-boned my car and almost totaled it. Having worked on cars all my life I replaced the two doors, rocker panel and B-pillar, pocketing $6k. Figuring the car was mostly depreciated, I dropped collision/comprehensive coverage and started using the cheapest oil I could find, many times Walmart Tech something. I was still changing the oil on the manufacturer's normal use recommendation. At 180k miles the engine was still running great, but the car was otherwise starting to wear out. I then doubled the change interval and the car just kept going. At 260k miles the car was rear-ended and totaled, but the engine was still the strongest part of that car. I've never paid for anything more than the manufacturer's recommended oil since and I've never had an oil caused failure.

I just use the cheapest oil from the local supermarket, just change it more often (3-3.5k miles). I don't know if I'm slowly destroying the engine, but I had no issues so far.

[@thesleepyweasel3775]

"No issues so far" is the warm fuzzy feeling that comes back to bite a lot of people. Too many drivers go ahead and use the wrong oil, and think it must be OK because the motor didn't immediately explode. Now, "slowly destroying the engine" is the right way to look at it. No engine lasts forever, but if you could get 500,000 miles using proper oil or 100,000 miles with the wrong oil, wouldn't that be worth taking a moment to make good choices? It's not always about the engine, either. I've seen a few dozen people use commonly available diesel engine oils in Mercedes BlueTec engines. 2500 to 3000 miles later they have warning lights going off and are looking at $4000 to $6000 in emission equipment repairs while the motor is fine. That's an expensive mistake.

[@boo_]

@@thesleepyweasel3775 I agree, however I am not using the wrong oil - it's correct viscosity - just a cheaper supermarket brand. Also, I've only paid about £630 (870 usd) for the car, I'm not buying top shelf oil for it.

Interesting. In our spec Miata race series we also change oil after every other event - or about 4 hours of running but we're using mostly standard engines and we want them to last several seasons. We use basically any decent 5w30 oil - any advantage to using a race oil in this application?

[@LubricationExplained]

You might get a very slight HP advantage with a racing oil. The SAE viscosity grade is a reflection of the bulk oil viscosity, but at many of the lubricant film interfaces (piston rings, cams, crank case bearings etc) what really governs the friction is the traction coefficient. Racing oils tend to be formulated with better base oils (mPAO vs cPAO or Group III) in which the lubricant molecules are able to slide past each other more easily in the contact zone. That reduces friction losses and help milk a couple more HP.

[@RadicalUnderdogs]

@@LubricationExplained Good info - thanks. So much of what people do is influenced by what they see others doing in the paddock rather than science. A couple of hp is almost equal to a couple of percentage points in a series like mine :-D

I run my highly prepared classic cars with "racing oils", which means tons of zinc, 10w60 (yes, this exists !) for easier cold start compared to 20w50 and higher oil pressure when hot (and bothered) in the summer. My classic mini with its A-Series pushrod engine revs up to 8k rpm when needed (=when I need to hear a beautiful sound) but rarely sees over 7k even when driven hard in those french B-roads and high viscosity, high quality oils are a part of what helps this engine not grenading itself, considering it only has 3 bearings. For road use, go thick, you don't really need those 2-5% theoritical increase in HP, and you will keep those horses for longer.

When I got my first Alfa Romeo back in the 1980s the official recommendation was 10w50, but you couldn't buy it where I lived. Fortunately it was rare to need to start the engine in freezing temperatures, so mostly used 20w50. Later on had a race prepared Alfa and sometimes used a 25w50 Pennzoil, which is what the engine builder had used. One again, not too many cold starts. Having 10w60 available these days is kinda crazy.

I am afraid there is nothing to debunk. When you think about it, you can notice a difference in strain that needs to be put on an engine to do certain amount of work, between smaller engines and their bigger counterparts, and we are talking about performance cars, those are not going to be driven in calm manner. On top of that i need to specify that i am writing about engines wearing out

[@LubricationExplained]

Smaller, turbocharged direct injection engines experience low speed pre ignition (a form of engine knock) much more than large engines, so there’s definitely something to the myth. In fact, the major OEMs (Ford, GM etc) demanded the new GF-6 engine oil spec specifically to address LSPI because it is becoming so widespread. Effectively, at low revs / high load (acceleration phase) the fuel dumped into the combustion chamber dilutes the engine oil and you get a volatile mix that self combusts before the spark plug fires. The pressure wave runs in the reverse direction of piston movement and can tear apart the top landing pretty quickly. Lubricant chemistry also seems to play a part - so in GF-6 oils the detergent chemistry is moving away from Calcium to Magnesium. Hope that helps a bit!

[@hessedkamanagi4592]

If you look at engine rotations per mile, it’s often engines that run at lower rpm that last so long. If the same engine had to turn 50% more in a lifetime it would wear more. Aircooled VW engines always live a shorter life in busses than beetles. Busses are geared higher and are heavier. I think it’s a given.

[@ryanbrown918]

Valvoline VR1 is the oil most flat tappet or solid lifter engine users turn to

[@thomasfortner6678]

Jason, I have two "older engines" that need more ZDDP because they are both flat tappet engines. My 1994 F150 has a 300 CID inline 6 cylinder that has had Valvoline synthetic since it was new. It now has 417,000+ miles on it with only one minor overhaul. At 235,000 miles, it was leaking enough to justify the overhaul, and a new cam and lifters were required because of minor cam lob scoring and concaving of the lifters. It is about ready for its second overhaul now. I don't use ZDDP additives or racing oil in it because it is reasonably nice to its oil. My other old engine is a 1966 Chevy Corvair, which has an air cooled 6 cylinder boxer engine. Because it is air cooled, it is much harder on oil, and I've used racing oil in it since I overhauled the engine 5 years ago. The higher ZDDP content and the need for higher viscosity are the reasons I use racing oil in it (Valvoline 20W50). GM originally recommended 30W high detergent for it in most climates, but as we know, 30W is hard to find these days. So, since some of us "old engine" guys are faced with changing oil standards due to changes in engine technology, maybe you could create a video for us on this subject.

[@verlaryder]

Wow, Toyota engineers would get a good laugh from reading your post about your "famously durable" Ford 300 CID that needed overhauling at 200,000 mile intervals because even as far back as 1975, Toyota engine valve trains were designed to still be unworn at 500,000 miles.

[@thomasfortner6678]

Verlayder, Ford straight 6 engines oiled the camshaft first and the crankshaft second, so any lubrication issues show up on the camshaft first. I could have reused the camshaft and lifters, as there was no clatter and wear was minor. I've reused camshafts that were more worn than this one, but since I was already inside the engine, I replaced parts that help me track wear in the engine.
