BP precat engine oil

DaiLoS323F · 25-12-2007, 04:44 AM

Hi! I have been test oil with my BP precat engine. I usually run with the car, but always hope 15 or 20 minutes to be able to give strong the accelerator. The engine has new valve seals, the compression test is perfect, never smokes (only in cold), all correct. Here they are my conclusions:

BP Visco 5000 5w40 = 2962km (3.8 + 0.9 = 4.7L oil)

BP Visco 3000 10w40 = 3076km (3.8 + 0.8 = 4.6L oil)

Mobil 1 5w50 = 4027km (3.8 + 0.9 = 4.7L oil)

Castrol GTX 15w50 = 3000 (3.8 + 0.7 = 4.5L oil)

Mobil Super M 20w50 = 3000 (3.8 + 0.2 = 4L oil)

My father has an Astina 1.8 GT precat with the newly repaired engine, and happens to him like to my.
Where I live, the temperature usually is between 10 and 45 degrees.

Are the BP precat engine like that

Thanks

the oil could just be from the crank vents going back into the inlet , tiny amounts of blowby and engine vacume will suck it in and burn it

im going to run full Syn oil in my GT engine, can give extra 4hp in the revs

DaiLoS323F · 25-12-2007, 08:55 PM

With a oil catch tank, can the engine burn less oil???

dave0r · 26-12-2007, 08:36 AM

yes a catch can will help with some of the oil burning if its coming outa the crank/head vents

DaiLoS323F · 27-12-2007, 02:51 AM

In January, I will bought a oil catch tank, I will comment the results

Thanks

Too thin / low weight oil for your engine - 5W, 10W and 15W all had 0.7-0.9L lost... 20W oil only had 0.2L lost.

Tried a 25W oil to see if amount lost is less?

You are right, but I believe that 25w isn't good for hydraulic lifters (when engine is cold), true?. Of all ways, there isn't 25w50 oil for here.

I'm going to make the last oil test with Pennzoil 25w50 (ebay), If it loses oil I will be definitively with 20w50 (BP or Castrol)

Lawsy · 27-12-2007, 05:43 PM

Use HPR15... Its a 15w-60.

If you look a little closer to what he has done, on all of the xxw-50 oils he used less, its just that with the 5w-50 he did an extra 1000km's, thus the higher result (since the engine is more likely to lose oil when the oil is older, as its lubricating properties start to deteriorate the oil will find it way past seals easier also.

Anyways, my point is that from your results, a 15w-60 oil is probably going to be ideal.

Try running the nulon performance engine treatment with your next oil change as well, and see how your results are then.

It might just be what your motor needs. I know mine uses less oil with the HPR15 and nulon, it also feels countless times smoother and is more eager to rev also.

See how you go.

This is what I have used for the past 50,000km. I have had no issues with lifters. Some oil loss.

15w60 is a synthetic racing oil... it's very expensive! I think it isnt' worth the difference, I will go to 25w50, but... what makes the nulon??

zappy65 · 28-12-2007, 05:48 PM

Nulon is a brand! they make great oils and lubricants, they also make products that help prevent wear etc...well worth the extra bit of pennies on your new ride...Im not sure whether you can get it in your country though?

DaiLoS323F · 29-12-2007, 01:07 AM

Where I live, it is difficult to obtain Nulon, I have never seen

I work at Supercheap, I sell oil every single time I work, and HPR15 definately isn't a racing synthetic oil, its a semi synthetic and costs about 33 bucks for 5L...
Nulon additives are sold at EVERY major car parts/accessories store.
If you can't find either then you didn't look at all.

you realize he lives in spain didn't you??? you realize that they sell different products accross the world don't you??? if you didn't look at where he was located, then you didn't look at all. you just made a ass of yourself.

DavoAust · 02-01-2008, 06:23 PM

a huge ass infact, seeing as nulon are an australian company and don't export as far as i've been able to find out. their products only seem to be easily availible in aust and nz. maybe you can find a specialist importer in spain but it would cost $$$. there are lots of alternatives to nulon, ask around to fine the best one availible to you

DaiLoS323F · 03-01-2008, 12:58 AM

In Spain, there isn't Penrite Oil, the most seemed is Castrol 10w60 and is worth 100$ AUD (60 €)

DaiLoS323F · 03-01-2008, 08:07 AM

I found a antifriction product, Metal Lube (say it is the best), I guess it is similar to Nulon, and it's possible that the oil loss decrease. On Friday, I change the oil, BP 20w50 + Metal Lube, when making miles with Metal Lube I tell my experience

Lawsy · 05-01-2008, 02:13 AM

Indeed.

The problem here is, I thought this was an Australian forum. And looking at everything, with all things considered, I'd say I'm not the first... or the 50th, or the last, to have assumed that...

My appologies.

project.r.racing · 05-01-2008, 07:39 AM

Yup it is an OZ forum, but the are lots of international members and there is even an International Section within this forum. Takes 2 secs to look at their location under there user names... Look, you are from Sydney! I looked. We have a few members from England, Belgium, Netherlands, Spain, Germany, Austria, Poland, Indonesia, Malaysia, Thailand, Taiwan, Hawaii (US), USA, Canada, South Africia, Israel and New Zealand from memory. There could be more???

On topic:-

DaiLoS323F - I do not think a antifriction product will stop your oil usage. There is overiously a seal, or rings that isn't working properly. I'd be investigating those options.

And I'm leaning towards piston rings or valve stem seals due to the fact that thinnner oils are lost more quickly than thicker oils.

Ryan

DaiLoS323F · 08-01-2008, 02:51 AM

My engine is perfect, it was compression test recent mileage and is perfect, and new valve seals. The 1.8 BG my father was repaired recently and acts like mine, his BP precat engine oil loss from new. Or it could be the climate for here.

Another thing... There is a problem because I'm not Australian? If I have to go the forum will do it, no problem...
