Current Penrite has bugger all zinc.
Its fine if you just want it for a daily.
I use a combo of 50:50 Gibbs XP3 and XP6, to give a little more viscosity.
Need to be aware of what you mix with what.

Do a bit of research on Diesel oils, different ash and detergent formulations, and higher zincs.


You had better look up the Penrite site Jason, they have had some high zinc oils available for a while now  :P

Reviving a bit of an old topic here.

Does anyone use Redline engine oil in their L-series engines. I've found some specific ZDDP levels when used with the break in addative which can be run all the time. See attached images.

The only concern is have is it states a minimum operating temp of 107degrees?

I use the gear oils in my diff and RB box and they are fantastic. Yes it is exspensive, but it would appear that it lasts much longer than most oils and provides superior protection. According to this anyway http://www.4x4austra...-long-life-oil/

I contacted redline and asked about suitability of their performance engine oil for a Datsun L28. I specifically asked about the 20W-50, their reply...

"Thank you for contacting Red Line Oil, in your Datsun we would recomme3nd allowing the rings to seat with a petroleum oil before switching over to our product, we do sell the Engine Oil Break In Additive that can be used to fortify and increase the phosporus level for cam protection. Once the rings have seated the 20W50 could be used though likely higher viscsoity than ideal, if internal clearances on rods and mains is reasonable the 10W30 would be recommended"

10W-30 seems pretty thin to me?

And, what Parts Per Million of zinc in their Redline, and for Penrite?
Stuff all!

There are oils that run far higher zinc content,,,,

In the case of the Redline oils it's all listed above in the screen shots.

For a 5ltr capacity their oil with 473mls of their ZDDP addative comes in at 2200ppm.

What are the specific figures on the blend you use Jason, it's certainly been put to the test so that should be a good indicator?

I kinda like that number.
Certainly shows on teardown

Keep in mind that ZDDP is consumed during engine operation so the PPM is not crucial unless the oil is going to be used for a longer time. And of course ZDDP is only one additive among many, base oil quality is the most important factor too.

http://www.motorweek...inc_in_your_oil short expert comment on the amount of zinc needed, too much performs no useful function and can actually be detrimental. Much more relevant to flat tappet engines too. Basically 1,200 PPM is sufficient for running in, 800 PPM after that.

On the first attachment it refers to 'total anti wear' it's a combination of ingredients and not Zinc alone.

Yeh, aftermarket adding ZDDP to oil is at best hit and miss, personally I have every confidence that Penrite can supply engine oils for every purpose. Spoke to a tech bloke there a few years ago, they were right on to racing needs and have since released a range of ZDDP enhanced oils for various purposes.

 

They are not the only ones of course, I just prefer to support a good Aussie company.

Yeah, I had a chat to Peter MC earlier in the week and he believes that L-series motors do best with a good mineral oil versus synthetics.  He recommended Castrol Edge 25w-50 which is the only mineral oil in the Castrol Edge range. This viscosity is in line with what the factory recommends for L-series motors too.

I can't comment on its ZDDP content because they do not disclose it and google searches have revealed nothing.

 

An old thread but worth a refresh by adding that Les Collins also recommends the Castrol Edge 25w-50.

A mineral oil with zinc that is better for L series engines.

Funny someone revived this thread, I was reading through the forum (didn't find this thread), but found this thread instead where a few people suggested the penrite HPR30 20W-60, as I was trying to work out what would be best for my bus.

I use HPR 30 and haven't had any issues. I don't know how much better the Castrol oil is but I'm happy to support an Australian company like Penrite which make great oils and support the classic car community.
