GT6 M Posted July 22, 2017 Share Posted July 22, 2017 Quoted from 1968Vitesse25 So, can we get a fully synthetic oil with enough ZDDP? Yip, 2,200 PPM ZDDP its good stuff too Penrite racing fully synthM Quote Link to comment Share on other sites More sharing options...
1968Vitesse25 Posted July 22, 2017 Share Posted July 22, 2017 On the Canley Classics catalogue, this is the factory installation for an oil cooler on a Spitfire.https://www.canleyclassics.com/triumph-spitfire-mkiv/1500-oil-cooler/ Quote Link to comment Share on other sites More sharing options...

They speak English BTW.http://store.moparshop.de/en/P.....-Zinc-Plus-0-5L.html Thanks!In fact I bought some of Lucas's own, ZDDP-rich, 'break-in oil', for less than £10 more than that.You couldn't make up your own for that!John Quote Link to comment Share on other sites More sharing options...
1968Vitesse25 Posted July 22, 2017 Share Posted July 22, 2017 I'm assuming you want the ZDDP to beef up your racing oil? Quote Link to comment Share on other sites More sharing options...

Jonny-Jimbo Posted July 23, 2017 Share Posted July 23, 2017 Quoted from 1968Vitesse25 The laws of engineering applies exactly the same to a 1907 De Dion as a 2017 Ferrarri.. But the actual designs, technology, manufacturing etc have all changed. Quote Link to comment Share on other sites More sharing options...
Nick Jones Posted July 23, 2017 Share Posted July 23, 2017 Here's a very reasonably priced 20/50 with decent (1,300 ppm) ZDDP levels. I've read that much over 1,100 - 1,300 ppm ZDDP is pointless, even counter-productivehttp://www.classic-oils.net/Classic-Oils-Heritage-20W50Nick Quote Link to comment Share on other sites More sharing options...
1968Vitesse25 Posted July 23, 2017 Share Posted July 23, 2017 Quoted from Jonny-Jimbo But the actual designs, technology, manufacturing etc have all changed. An engines an engine, it's the same principles.Coldest air in, hottest air out,We have a far better understanding of the physics, but it's all the same rules.Keep your coolant hot, but don't let your oil get too hot - and Triumphs pushrod engines have always had an issue with oil temperatures.A combination of a basically poor design stretched far to far and a domestic market that didn't force mass manufacturers to address oil breakdown during high speed running. German and Italian cars of the period were far more durable thanks to their markets need to run on Autobahns and Autostrada.Triumph were well aware their engines had issues with oil temperatures when they started fitting as standard or offering oil coolers as a dealer fitment for cars being exported to the Continent and the USA in the 1960's.

sparky_spit Posted July 23, 2017 Share Posted July 23, 2017 Quoted from Spitfire6 Hi, I would not be wanting to add extra ZDDP to an oil even if the additive was free. Maybe on a new rebuild, But I would not be using an expensive oil for the first couple of hundred miles.. Yes, totally agree for normal running using proper quality oil for our engines but this is for running in a newly built one. I was trying the find the right balance between oil that was suitable to allow rings to bed in without glazing, while having enough ZDDP in there (via an additive) to try and protect the cam and followers.I was planning on using something like Comma Motorway 20/50 (dirt cheap I know, but that's not the point) and a ZDDP additive in the right proportion.However, looking at the link in John SB's post re Lucas Oils, their break-in 20/50 seems to be ideal, so I'll use that for the first 200 miles.

1968Vitesse25 Posted July 23, 2017 Share Posted July 23, 2017 For breaking in an engine, you actually want a pretty 'poor' oil without all the Gucci modern anti wear additives to let the engine and most importantly the rings bed in. The ZDDP is to protect the cam during bed in. Most 'break in' oil is just that, a basic Dino oil with ZDDP. Quote Link to comment Share on other sites More sharing options...
