Penrite Oil 10 Tenths Racing 10W-40 (100% Pao & Ester)

5w-50 AUDI 1.8T this oil I have found to revitalise AUDI/VW turbocharged 1.8t engine – I deal a lot with the audi/vw 1.8t and I found this oil (5w-50) by trial and error when I had to deal with a high mileage 1.8t 300,000 km. I was having trouble with this engine as it would blow smoke and I had trouble getting oil pressure once warmed up. It gave me the oil pressure I needed hot and cold where other high viscosity oils would not… Read more ·  1

flow at cold start and gave cold start lifter tick. I also had problems with oil burn from turbo seals and shortly after using this oil the oil in exhaust disappeared. This oil is very quick flow on cold start (I first noticed that it poured very thin when adding to the engine- this is a good thing, it needs to be thin on cold start) I now recommend it to all my 1.8t customers and have had positive feed back that it has given the same results in other 1.8t. I also run many 1.8t with e85 and high power high rev turbo 4cly at 500hp.

It DOES have Hi ZDDP which is great for the 5valve per cylinder 1.8t with its old school cam lobes direct driving the lifters- BUT long term use will not do your cat any favors - I mostly run e85 so my cats do very little work and I'm not concerned.

Best on the Market – I use racing 10 in my s13 Race car and early on in its development we had cooling issues (rad was too small) and the Penrite racing 10 held up perfect even in extreme temperatures, Now we have car sorted oil temp and pressure is perfect. Also the fact it is a true synthetic oil makes it a no brainier for my car.  Show details ·  1

Can't speak highly enough of it – Using the 10W60 variant in my turbocharged 626 (was using 10W70 before being discontinued). Lifter noise non existent. Builds pressure quickly and maintains during extremes of operation. Blown head gasket and head was perfectly straight afterwards, some of which I attribute to the properties of this oil. Can't review it here but my wife is using… Read more ·  1

another synthetic Penrite product and has negligible compression loss after 280,000KM of use.

I used to be a Castrol user but Penrite products seem to result in quieter engines with less wear. Being Australian owned is a side bonus.

Best I've used by far – Been using the racing 10 on my 1993 R33 gtst with 300 rwkw for years. I've owned this car for 14 years now. Used to use that French brand but not anymore. Keep up the good work Penrite. What a way to Support An Australian company and get a great product.  Show details ·  1

Great engine oil – I have been using PENRITE 10 RACING 10W40 Engine oil in my 07 Evolution 9 for over 2years now. Never encountered any problem, oil burns or leaks nothing whatsoever. Car is slightly modified with 251kw @ all wheel. Engine is very quiet, very smooth and power and torque delivery is great. I switched to Mobil 1 0W40 a couple of times in winter and I… Read more ·  1

didn't notice any difference. I replace oil very 5000km or under. I had to contact penrite in choosing the correct oil grade they have been very helpful and very prompt and spot on.

If you love your car then penrite will keep it running smoothly for miles and miles..

They are a bit pricey especially of the grade I need, but I don't think people buy EVO and feed her with inferior quality Engine oil.
