240Z_au Posted February 16, 2015 Share Posted February 16, 2015 Hi there.. Just completed 300 miles running-in period on my warmly tuned L28. With mild cam, triples and a need for a frequent 7000 RPM, I need oil which will stand up to the task. I saw a few recommendations on Penrite with their high Zinc content, but I see viscosity varies and they dont seem to have a 10W-30 which I'd like to use in my engine. I see there is Valvoline 10-30W with high ZDDP, but they don't seem to offer this oil in Australia. Thoughts/Recommendations on the above?. Who uses what in their modified/hard working engines. Thank you in advance. Andrew. Quote Link to comment Share on other sites More sharing options...
dat2kman Posted February 16, 2015 Share Posted February 16, 2015 Look at Joe Gibbs, LAT Brad Penn All have high Zinc, way way more higher than the so called commnly available "high zinc" oils in the shops. I use Joe Gibbs xp3/xp6 in ,y engines, extend oil changes, by factor of four, oil ressures and temperature are a little more stable, and on engine tear downs, nowhere near the amount of wipe on bearing shells, compared to your "super dooper modern" stuff.

240Z_au Posted February 17, 2015 Author Share Posted February 17, 2015 Thanks very much. I never considered these brands, my head has been stuck in modern engines for too long so outside the odd Royal Purple, I saw nothing but the mainstream brands. I checked both the Brad Penn (impossible to buy here, Motorsport Connection in Sydney have no stock till Mid March and another supplier in Melbourne main number is diverted to a mobile) Then I looked at your Joe Gibbs recommendation, but that's fully synthetic which I guess is where you get the clean tear down benefit from I guess. XP3 looks good, just not sure if Fully Synth is the way to go on an older style engine?. You run low micron oil filter? Quote Link to comment Share on other sites More sharing options...
pauly_adams Posted February 17, 2015 Share Posted February 17, 2015 why are you after such a thin oil ? also penrite's scales is a bit odd so HPR5 will be a 5w30 or 10w30 equivalent http://www.penriteoil.com.au/products.php?id_categ=1&id_brand=1&id_products=1 Quote Link to comment Share on other sites More sharing options...
260DET Posted February 17, 2015 Share Posted February 17, 2015 Penrite would be my choice. Quote Link to comment Share on other sites More sharing options...
240Z_au Posted February 17, 2015 Author Share Posted February 17, 2015 So you all run fully synthetic oils?..The old 1970's recommendation was a 10W-40, but of course 10W-30 is thinner and will allow freeer spinning and get to the bearing parts easier, etc. I want an oil with higher ZDDP levels and I see Penrite states "FULL ZINC", but when you look at spec sheet it only contains 0.10%, whereas I'm looking for more like 1%+. I'm afraid mainstream oil manufacturers need to eliminate higher Zinc levels because they need to conform to the modern EPA standards so Penrite is out for me. I hope I'm not getting too pedantic here, but I do hammer my engines and race them regularly so I need the best protection I can get for the older style engine.

dat2kman Posted February 17, 2015 Share Posted February 17, 2015 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. Quote Link to comment Share on other sites More sharing options...
240Z_au Posted February 17, 2015 Author Share Posted February 17, 2015 Thanks..Yeah, I agree re diesel oil, just feeling mentally not ready to run industrial lubricants in my Z , but I agree, they tend to have more of the good stuff. I may just go with your other recommendation. So fully synth all the way for you?. Where do you get a good supply base from in Australia? Thanks in Advance.

dat2kman Posted February 17, 2015 Share Posted February 17, 2015 Google Joe Gibbs Oils, shoot them an email asking for the Vic distributor. Our guy up here is two suburbs away, they mainly supply speedway and drag race customers, maybe ask similar Speedway/drag type suppliers/shops down your way?

pauly_adams Posted February 18, 2015 Share Posted February 18, 2015 I personally run penrite HPR15 15W50 in my z the engine is fairly fresh and can at times cop about 18psi of boost up its back side, the other oil I use is Nulon 15w50 street and track Quote Link to comment Share on other sites More sharing options...
240Z_au Posted February 18, 2015 Author Share Posted February 18, 2015 Thanks Guys!..Checked Joe Gibbs, but because they apparently changed the name to "Driven" I couldn't see any local suppliers easily. Got two gallons ordered now..Will be cooking this weekend .. Thanks again. Quote Link to comment Share on other sites More sharing options...
Roberto Posted March 15, 2015 Share Posted March 15, 2015 The Penrite 10 tenths range has at least 2200ppm ZDDP which is nearly double the Penrite HPR range. Ie 0.1% zinc vs 0.2%. http://www.penriteoil.com.au/products-categ.php?id_categ=1&id_brand=3 No oils listed in this thread match that in zinc content. I want an oil with higher ZDDP levels and I see Penrite states "FULL ZINC", but when you look at spec sheet it only contains 0.10%, whereas I'm looking for more like 1%+. What info are you referring to that makes you want 1%+? I haven't found any motor oil with zinc more than 0.2%. Quote Link to comment Share on other sites More sharing options...

I've been led to beleive that mineral oils are better for the older L series engines Also, 15W-50 or 20W-60? Quote Link to comment Share on other sites More sharing options...
dat2kman Posted March 16, 2015 Share Posted March 16, 2015 I think you'll find that the Joe Gibbs, Brad Penn and LAT oils are the highest zinc content. Commercially available in Australia, and come in a range of viscositys, or single weights, and in both pure mineral ( Pennsylvania State) as well as compunded Synthetics. As for what to run, it depends on clearances and tolerances, and what type f kechanicals are within in engine. Eg, a multi valve cam on bucket, or cam n follower with very tight tolerances, desigined for high rpm, ie Toyota 20 V 4AGE would use a 0-20 weight range. An older cam on rocker, or cam to hydraulic lifter, large soze two valve head, bigger bore, looser clearances, ie a Ford/GM V8, or a Nissan L series 20-60 weight range. Its quite possible to run a single weight viscosity oil, f you know what your ambient conditions are, and bring an engine to operating temps before use. Heavy oils are sluggish and reduce an engines ability to perform well compared to much lighter weight oil. It's never been rocket science.

Roberto Posted March 21, 2015 Share Posted March 21, 2015 This is a full synthetic oil. I've been led to beleive that mineral oils are better for the older L series engines Also, 15W-50 or 20W-60? 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. Quote Link to comment Share on other sites More sharing options...
Roberto Posted March 21, 2015 Share Posted March 21, 2015 http://datnet.org/topic/14125-castrol-q-a-thread/ More searching has found this thread. This website indicates Castrol Edge 25w-50 is at lesast 1000ppm zinc. Quote Link to comment Share on other sites More sharing options...
ZED660 Posted April 10, 2015 Share Posted April 10, 2015 Another option is Pennzoil GT Performance Racing Oil 25w/50 which is still available from these guys http://www.kynuna.com.au/index.htm Quote Link to comment Share on other sites More sharing options...
HKSZ Posted April 10, 2015 Share Posted April 10, 2015 I run 25/50 Pennzoil GT in my rally car, plus I add Nulon e20 engine treatment to this and all my old engines. Quote Link to comment Share on other sites More sharing options...
dat2kman Posted April 10, 2015 Share Posted April 10, 2015 Oils i use range from 8000 to 10,000 ppm. Kinda nce insurance to have. Penzoil GT has always been a favourite of Stew Wilkins at SWM. Hard to find their old formulation good stuff Quote Link to comment Share on other sites More sharing options...

Riceburner Posted November 18, 2015 Share Posted November 18, 2015 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.4x4australia.com.au/gear/electronics-gadgets/1102/red-line-long-life-oil/ Quote Link to comment Share on other sites More sharing options...
Riceburner Posted November 21, 2015 Share Posted November 21, 2015 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?

dat2kman Posted November 21, 2015 Share Posted November 21, 2015 And, what Parts Per Million of zinc in their Redline, and for Penrite? Stuff all! There are oils that run far higher zinc content,,,, Quote Link to comment Share on other sites More sharing options...
Riceburner Posted November 21, 2015 Share Posted November 21, 2015 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? Quote Link to comment Share on other sites More sharing options...
