Royal Purple in a DeLorean

Brave man, inviting a synthetic vs. conventional war.... ;-)

It's going to come down to preference in a big way. I wouldn't use synthetics in my D because I'd be worried about allowing the seals to leak. But that's me and everyone will have different opinions and different reasons for having them... :)

Cool, well, let the discussion begin. I'm interested to hear everyones opinion and reasoning.

Well, you see my rationale above. Royal Purple is a great product with a great reputation; but I think its place is in newer, more modern engines. Synthetic oils (though I do realize that RP is a synthetic blend) have uniformly sized molecules, which can allow seals that previously didn't leak to start seeping. If you have a newly overhauled engine with all new seals you probably won't have a problem. I definitely do not have that luxury and would be wary of switching from conventional oil.

If it ain't broke, don't fix it.

[vwdmc16]

ive run it it a few of my cars before, I saw no visible or feelable difference besides my wallet being much lighter.

[Nicholas R]

I've been running mobile 1 for several years and never had any problems. I typically use their 15W-50.

[nofear365]

+1 to what everyone said about not needing synthetic oil in these cars.

[Dracula]

I use Royal Purple in my DeLorean and have no leaks or issues whatsoever. As long as you transition properly and change the oil regularly, it's really not that big of a difference.

Royal Purple is used by racing enthusiasts al over USA.

Don't know if that leaking stuff is true or it is just a myth. My sons use it on their old chevy/ford vehicles with not a leak.

I would think, you can safely use it, if you seea leak right after starting with this oil, then go back to whatever you had before.

Just remember, Royal Purple is not a miracle oil, it needs to be changed as often as the regular oil. If you switch to Royal, don't rely on the color of your oil as "time to change".

Now, if you are looking for a miracle oil, then switch to Amsoil!

It's not a myth, the scientific principal behind it is sound. It's more a matter of whether the conditions in your specific application will permit the leaks or not. If your seals are fresh and good, you shouldn't have a problem. If your seals are already on the verge letting go or if the material they are constructed from is more porous or susceptible to permitting uniformly sized molecules through, you will see leaking.

It won't be like in a cartoon - drain the oil and put the synthetic in, then a geyser erupts from every seal. You'll just see slow seepage, and again - only if the conditions are right. I just don't tempt fate, even if the synthetic oils might be better for other reasons.

If your engine start to leak right after Royal, then you can always go back to your old oil, right?

Is not that Royal will ruin your old seals.

That isn't a question I have an answer for. Probably not though. But then you get into the expense of Royal :) Draining it right after filling might not suit everyone's budget

I've been told you cant go back to dino oil after synthetic because the oil clumps and turns to sludge - no idea if its true but it is enough to scare me...

BTW - a little something for Farrar:

Through many discussions with Rob Grady and lots of other DeLorean and classic car folks, The additive package in conjunction with the weight is most important for our cars. We had a really great discussion about oil a while back that brought out alot of good points:

http://dmctalk.org/showthread.php?265-ZDDP-Plus&highlight=zddp

The jist of it was bascially any oil with the CJ-4 rating is ideal for use in our motor. This is mainly found in heavy Diesel motor oils like 15W-40 Shell Rotella or Mobil Delvac. I've been running it ever since with no issues at all.

Don't waste the money stick with what works. Odds are you probably won't own the car or run the engine long enough (300-400,000 miles) to see a noticeable difference anyway.

That's what YOU think. I intend to drive the car until there's no life left in my flesh.

Well I said "Odds are" but there are exceptions to every rule.

Umm.. excuse me Mr. Dracula is it? Are you technically alive? I realize you're immortal, but the undead don't have living flesh, unless its something they are flossing out of their teeth. I mean no offense. Please, don't drain me for bringing this up...

I've used synetic oil in my air cooled Volkswagen in the past and have noticed a temperature drop in the engine but other than that, not much more.

What was said earlier is true, the chemical makeup of Synthetic oil is much smaller hence the reason your more likely to have seals leak. On newer engines (or rebuilt) you should be able to run synthetic without any issue but with older engines your taking a risk.

Ah, this old question. Note I said "...until there's no life in my flesh." The blood is the life, the coin of the soul by which we pay the ferryman of the River Styx. I never said it was MY life.

Joking aside, I use an antiquated vernacular that tends to be overly eloquent and it goes well when I play upon my Transylvanian heritage; it is the most apropos of the seasons.

There is no good reason to overpay for what is supposed to be "better" when you should be changing it out way before you wear the oil out. Syn is better for vehicles that get more mileage and you want less frequent changes. Not the case in older classic vehicles that get a lot of maintenance and low mileage. There is not much chance of doing harm so use whatever you want as long as it has the proper classifications for the application. In the long run you will not notice any difference since in most cases the car is used on a limited basis. If you insist on overdoing it then just change the dino oil more frequently and use a good brand.
