The Porsche 993 series 911s from 1994 through 1998 had a production fill of 10W-40 Mobil 1. (yes the 993 3.6l had CATs). The M1 formulation of that day had approximately 1,700PPM ZDDP - ZINC. .. Fast forward to year 2024 what to do? .. The M1 10W-40 or the M1 15W-50 formulation has much less ZDDP,,, in the range of 1,200 PPM.. What to do?

Does Driven make a V twinn semi syn?

Since zinc is bad for your catalytic converter, what would you suggest to run in place of zddp?

What oil do you recommend for a LT4 with direct injection and Port injection for high boost?

good video, thanks a lot!!

Quick question, my lil 1.5 na honda fit DI works better the hotter the engine gets. Would going from a 5w20 to 0w20 help, hurt, or not make a difference in gaining horsepower? Thank you so much!

Still relevant today?

its been 5 years did we knew what is that 20w 50 oil ? i mean did the oil ever mass produce? curious how 20w 50 mineral stay cooler compared to 10w 40 syn :)

Do I need to do a cam break in if I did not install a new cam and tappets? I only done in frame on my 5.9 cummins.

I wonder if a cooler engine would help, like installing a 160-180 degree thermostat

Ive never heard of Driven oil.

Great info thanks

So what is the best break-in procedure for a new Mazda MX5. I dont know what valves they have in that 2.0 litre

I don’t get the fuel mixing with the oil? How does the oil get in the fuel in the first place?

Just watched your video on your daughter's car. Searched and found this. As I see this the question was will zinc damage my cat. Your answer seems to be that it can if it gets there. I use high zinc and phosphorus oils often and was actually led to believe it was the phosphorus that did the damage. Video is okay but I find the answer evasive.

How long does this oil last? 3k? 5k? What is the change interval?

How long will the oil last ? 3k? 5k?

I want to work with you. I want to help you grow your business

Lake, going to oil company spec sheets as well as the Owner's Manual, they list an "Approval", in the case of my Porsche, that is an A40. But is that a "specification" like API SN Plus for the 5W-40 grade? How does an A40 coincide with a specification?

Can you guys provide PDF spec sheets on your web site telling me what the ppm components are in your oils. Like what is the zinc, molybdenum, phosphorus, etc.

I spoke with their Engineers several times. They were very knowledgeable and easy to understand.

I drive a 1979 Buick with 3.8 V6 and use Valvoline Racing Oil 20W50 and the car still has to pass state emission test. So I am hoping the catalytic convertor will not be ruined. The engine is not using oil as far as I can tell. Just leaks a bit. Oil is changed every 800 to 1500 miles.

It might be a good idea to introduce yourself which you did and your educational background along with what college you went to. Do you have a degree in chemistry or as a chemical engineer. The trouble with the internet and RUclips is the fact that there are many on them that went to a pep-talk session about a product and have a good memory.

i m very glad to see the results it also hit mewhen the 20w50 temp is much coolder than the 10w40 my question is what does that effects on the main crankshaft journal oil holes ? does 20w50 lubricate much better than10w40 or has no effect so many contradiction in answers over the internet. did you use same oil brand for both tests ? wish to get a reply and thank you again for this great info . note: redited comment for grammar corrections

Well let's see here.... if I have a little money, but have a chance to have a lot more money... is that better? YES!!!!

Many oils on the Australian market have on the label: “extra 10% Zinc” for petrol and diesel vehicles with catalytic converters. The non/low zinc oils state “DPF compatible” ref Penrite Oils Australia. 🦘🇦🇺

It’s the same with Nissan. I bought a new 2020 Nissan Altima 2.5 DI non-turbo. I always buy new and always change out the first oil at 500-1000 miles. Thank god I did on this car. Not knowing the fuel dilution issue, I almost had a heart attack when I pulled the drain plug and the most horrendous fuel smelling oil came out. I wasn’t even trying to smell the oil. The stench was over powering. I truly thought my engine was toast. I immediately read online that this was “normal” for DI engines. Fortunately the problem seemed to fix itself after a few thousand miles. I change my oil with Pensoil platinum synthetic every 6k miles and the oil smells normal with a hint of fuel and it doesn’t seem to burn any oil either. I’ve heard that the 8k-10k oil changes on these DI engines are killers on the bearings and cam. Now, if your like me and trade in your car with under 100k miles then it probably doesn’t matter but buyer beware.

Soooo TRUE 💯 thank you!

This is why I only buy Toyota vehicles . They developed their D4S system of direct injection along with using port injection. Dual fuel injection system. Still have port injectors to wash the back of the intake valves. On the tacomas they even have a mode where the computer will put the engine into direct injector self cleaning mode to blow the carbon off the injectors while still being able to idle the engine using port injection. To top it off I run amsoil signature series in my Toyotas for added protection .

I only trust experience. And experience tells me, change oil often. Atleast by 5k.

Never extend drain intervals. Oil is cheap, engines not so much.

Liqui moly ceratec additiv is a safe bet.

I change oil every 5k and add Rislone nano prime.

My car can use both 5-30 and 5-40. If i use 5-40, will that make less wear than 5-30? But maybe slightly less fuel efficient?

I use GM dexos 2. Is that good?

Греат продукт, есть в продаже по СНГ?, куплю в ладу

What oil do I need for my HEMI 5.7 2007 for break-in ?

Where is the piston clearance to oil viscosity chart in the website ?

Which Driven break in oil do you recommend for a performance SBC with a solid flat tappet cam?

I used AMS oil break in worked great !

Still a great and relevant series.

Hi Lake. It's funny... I've been experimenting on some vehicles w higher zddp... Like in the 1600ppm range and so far no cat problems. If it does damage one, it will b worth the experiment to know for sure and for the extra wear protection on a motor. But here's my question.... I actually use mobil1 20/50 v twin motorcycle in a car without a cat. It has one of the best additive packages I've seen. It has the same Moly as other Mobil 1's and a lot of boron. Approaching 300 ppm. The zddp is around 1600. Aside from cat issues, this is one of the best oils I've seen on paper and can't see why it's not ok. I'm wonder what the base oils r... If they r group 4 and 5. It also has a high 20.8 viscosity and really good high temp performance and anti shear. The only thing I'm wondering, is that it has around 2200 calcium. Is that too much where it would counter the zddp and boron/moly? Or would u still expect it to b a really good anti wear and also a good cleaner. That film strength too.... Seems really good. Just that calcium question that's haunting me. And I do wonder about the base oils and what group they r. Any light u could shed on those questions and what u think of the quality of that oil, would b very appreciated. Thanks so much!

Is this the same as ZF Lifeguard

i have a Audi A6 3,0 TDI , with 430.000 KM .., only use 10w60 / Lucas Oil Stabi /ZDDP Midland… Drive often full throttle -full speed on german Autobahn with 260 Km/h … engine runs great ..and fast … my question… can I use it in my 392 Hemi ..? I now … Hemi has a roller cam …. Greeting from Germany

I bet engine clearances are not identical

Why is diesel engine oil different formulation? Is the a absence of a gasoline type of catalytic converter allow different formulation of oil with more engine protection additives with out damage to the emission systems? I have been told that a flat tapper engine requires protection form oil additives to limit wear. Did the reformulation of oil usher in roller camshaft use on a larger scale because of premature cam wear failure? What kind of oil should my 1973 Big Block LS4 Corvette be using for the protection of the camshaft?

11 years later, is NextGen PAO now just current-gen PAO?

I have an 86 dodge ram with a 318 LA engine flat tappets . I just got the truck and gave it its first oil change and added a quart of STP ZDDP Zinc additive with some SAE 10w-30 conventional oil. Is this sufficient enough to protect the lifters / cam or should I use a high zinc oil and just eliminate adding the STP additive ?

I had never even heard of Driven brand until a month or two ago. I knew of Joe Gibbs, so when I found out about Driven, I was very interested in their products. I tried out their GL4 80W90 conventional manual transmission fluid and it was immediately the best fluid I’ve run in my Tacoma transmission. I’ll probably be using their GL5 85W-140 in my axles next and will probably fill all my other transfer cases and transmissions with more of the 80W90 GL4. Good stuff!

Hello Jake, I have a question regarding higher octane and LSPI. If I use an octane booster to increase the octane level, does that help in any way to eliminate LSPI? I already use Driven oil and a fuel additive to help vaporize the atoms in the 93 octane fuel I use, but now I'm wondering if adding a octane booster will also help in eliminating LSPI in my 2012 CS 991.1 Thanks again for sharing your knowledge! I just moved the "Likes" to 205...this should be way, way higher for the knowledge you're sharing...come on Peeps, get with the program!
