Oil for Classic cars and the need for ZDDP

What is ZDDP (Zinc dithiophosphate) and why do you need it, or not? Our technician goes through the why's and wherefore's so you can purchase the right oil for your British Classic car.

i use rotella t4 10w30 in my 1970 318 and my engine loves it and yes it has the right amount of zddp for a flat tapped camshaft i believe 1200 ppm

[@neilduncan8657]

try the Rotella T6 it is a synthetic but has zinc/phosphate I use T6 and STP in my roller cam 302 (installed in a 84 Datsun 200sx!) The phosphate in the ZDDP does the actual lubricating

finally a new video. i missed your presence. the brake bleed and how to find a short. it really helped me fix my Ford Explorer. Keep up the videos

[@MantisManTRD]

Great video. Very helpful working on classics. I'm enjoying your channel.

[@adamledger1646]

I find these so helpfully and entertaining, please make some more :)

STP oil additive contains ZDDP enough for a 4 to 5 quart oil change, cheap and works perfectly,

[@Littlelewie151]

Watch project farm's video on UA-cam about STP. It is so low in ZDDP that it actually lowers your overall ZDDP count. Even in modern oil.

[@bitTorrenter]

@@Littlelewie151 It probably has a max of 5% I'd guess. At least Redline's product states exactly what it contains. Since I have a modern car, I wouldn't want to add an excessive amount and so one bottle would be good for 3 oil changes for me. At least that's what I'm lead to believe. With my oil tanks capacity (4.86 qts), 1/3 bottle would add 762 ppm Zn and 632 ppm P.

Racing-type oils from Amsoil or Lucas Oil are very high in zinc - worth the $$ if you care about your engine. They both also make high-zinc, non-racing oils

More videos, we miss you!

[@smoothoperator7306]

Thank You very much for information . For old lister cs 5 ör 6 which oil we must use ?

So what if you have a classic car, say a 1990s Mini, the engine design of which dates right back to the early 1950s. Minis produced in the final decade of production had catalytic converters, but with engines requiring ZDDP. What then?

[@rogerlittlejohn475]

HDEO's (heavy duty engine oils) such as Chevron Delo and Mobil Delvac have sufficient zddp for older cars, typically around 1200 ppm of zddp. They are also available in synthetic. 15W-40 or 10W-30 are good viscosities for your classic cars. I would not use a 20W-50 oil because it contains too much polymer (rubber) in that viscosity. The polymer will cause deposits in the ring zone and on the valves, shortening the engine life. Thats why you do not find 20W-50's in todays motor oils.

[@GeorgiGeorgiev-ne9ps]

Cat converter is worth destroying if the motor feels better

[@scatpack68]

Mobil1 15w-50 1300ppm of zinc

[@umangu]

Do 60s mustangs have catalytic converters?

[@gorkzop]

No, probably 73 uo

[@1997LT1Camaro]

Best is to but oil with zddp out of the gate

[@TheLARRYSUGGS]

I run rotella in my mgb 🤷🏻‍♂️

[@jasonroberts2049]

It's what separates men from boys, those who have courage and those who lack it. " I run from it like I would a fire"..Every fire I've seen, I get closer to try and save lives....

[@denniskwahl]

It would be nice if the speaker was understandable...very muffled.

[@jasonroberts2049]

I don't understand.... new cars burn oil???? My car has had 4.3qts of oil in for over 2 years. 15k miles later and I still have 4.3qts of oil... ummm new cars don't burn oil. Facts

[@spencer2652]

Lol 🤣🤣🤣

[@user-fs5lc2dl7t]

info very good....do without the jazz hands...doesn't convey any info and very distracting...
