Would you guys recommend using Ester Based Engine oil for 993 or other air cooled engine? Engine Oil such as Millers Nano Drive or Silkolene / Fuchs Titan Race Pro S or Motul 300v ?

 

Firstly congratulations on having only 3 posts in 14 years - that's what we call serious 'lurking'

...but oil threads on rennlist tend to turn into all-out war.

My advice is to look at your own type of driving, your ambient temperature of where you drive, and the number of miles your engine has done, and then look in the Driver's Handbook.

My opinion is that you should fit the oil that suits the purpose, and change it slightly more often than schedule.

 

Hi Etang,
Feel free to pour huge sums of money into your engine's oil tank if it somehow makes you feel good. For a street-driven car there probably is no practical benefit over a good Synthetic labeled petroleum product such as Mobil1 or similar. I use Mobil1 and purchase it when they offer a rebate and end up buying 10 quarts for about $26.

Well yes "lurking" is true, and it has just turned serious because I just bought my first Porsche! Will start another post about it later!

Thanks for the heads up!

Reason asking is most 10w60 here locally is not cheap anyways and ester based is about the same price. But I dont see much examples using it here...

 

Congratulations

I haven't been to HK for many years, but when I was there, a car was either parked, or in a traffic jam. This may be you, or you may be tracking the car, or driving onto the mainland. I'd do some research depending on this usage.

But I'm with Andy - fit for purpose.

Remember also that the Driver's Handbook, back in 1995/6, was written by the engineers who built the engine, not the Accountants or salesman, so there is some very good information in it.

 

DYOR but there is no 60 weight oil listed in my Driver's Manual, so for 'normal' use I would never put in a 60.

Another point of which you may be unaware - put simply, the bigger the gap between the two numbers on an oil specification, the more additives there are to achieve this range. So a 10w60 has more additives than a 10w40. DYOR.

There is yet another factor
modern oils are 'cleverer' than those that were in existence when the engine was designed, but modern oils also have to be cleaner than the 1990 oils - regulations for emissions for the environment. Look up ZDDP if you need to go to sleep.

Good luck.

 

I was looking at 10w60 because the Porsche Classic Motoroil is a 10W-60 oil

 

Yes indeed.

Opinions vary on why Porsche-of-today recommend this oil, that they market, in pretty cans.

Also, it is interesting that Porsche, from around 2000 to 2015?, recommended 0w40 in the 993.

I have decided, after doing my own research, to follow the advice of Porsche-in-1990s.

I use Redline which is ester based full synthetic in all my modern classic cars.

 

Motul 300V is ester based, and it has high ZDDP content (which is good for the air-cooled engines). I use it in my Ducati, and wouldn't hesitate to use it in my 993 if Brad Penn wasn't available.

 

I only use the Porsche Classic Motoroil 10W-60 oil.

 

Etang, have you ever seen a Brad Pitt or Sean Penn movie? Well, they co-developed an oil many years ago called Brad Penn. Good stuff. And when you look in the mirror in the morning, you get more handsome every day.
