Penrite 10 Tenths Racing Oil Questions & Answers

Absolutely

Just like to know what temperature the oil needs to reach to burn off fuel deposits and any condensation. The car has not run for a few years as it has been restored. I’ve got the engine running and I am going to get a new radiator and thermostat.

I cant be sure, if specifications allow it then I couldn’t see a problem with using it.

Thanks the Penrite MS4ST 10W-30 PAO & Ester is perfect in the lawnmower so Penrite said.Cheers

Absolutely, a running in oil is crucial to longevity of your engine.

According to Penrite's Oil recommendation chart you can use 10W40 Fully synthetic which is slightly thicker, these numbers are only marginal increments. if you are losing oil and your power has dropped it sounds like your rings are on the way out, given the modifications you have outlined this engine has been driven hard and is now giving up the ghost, Mazda & Mitsubishi rings are not renown for long life.

Whether your VY is a V6 or V8 it is starting to get "up there" in age. If you are changing your oil every 10,000 km's maximum or 12 months (Which ever comes first) your engine is fine. 0W40 is very thin and watery, it is designed for long service intervals while the vehicle is still under warranty, being thin reduces the risk of "Sludging" how protective it is for your engine is arguable, the friction protection properties have long since departed after 8,000 km's. A better oil for your vehicle would be 10W40 Racing Ten Tenths, check your Penrite recommendation chart on the web.

No. Higher Zinc is better for your engines bottom end. Reduced friction, longer lasting. Zinc has been removed from modern oils for the enviroment, not in the interest of your engine. Same As with low number oils, e:g 0W30 which has the viscosity of water, Car manufacturers are now claiming 15,000kms between oil change??? The thinner oil can extend that long without "Sludging" but it is not very good for your engine. Car manufacturers want you to get through your warranty period and then buy something else, not keep your car running sweet for 10+ years.

Sorry, I'm afraid to answer your question, I would recommend you to contact Penrite support on [email protected]. They are very helpful usually reply to emails on the same day. All the best

Penrite selector chart recommends 5W50 10 tenths racing oil for Porsche 911 Carrera 2 964 Speedster 3.6 Litre Engine (1989-1994). 20W50 seems extremely heavy for a "New" rebuilt engine. Although the viscosity in grades is not as huge as people think. 10W50 would probably be ideal. 10 Tenths racing oil uses New Pao ester oils so it is perfect for all cars. Go to Penrite oils website and shoot them a line on feed back questions, they are always very good.

Hi Mike, Yes this can be used in your car, has the engine been run in yet?

The Jap motorcycle engine is designed to be used with Castor based oils. So the 10/tenths synthetic oils are not suitable.
Castor based oils leave a wax layer still providing lubrication even when majority of the oil has been disposed. Try Castrol R 40, Newton R, Morris MLR 40, or Millers CB40.
Another is Silkolene R40 Classic. google Jap Engines 2 stroke & 4 stroke maintanence.
