Oil Comparison

[EURODESIGN]

Which of these two brands do tuners prefer Mobil 1 synthec or Castrol Synthec

[equipped2ripp]

it depends on a number of factors... engine type etc.

[3stagevtec]

i currently using Castrol Syntec and have no problems with it.. but between the two, i'd put Mobil 1 slightly ahead of Castrol..

[cacasplat3]

using Mobil1, never used the Castrol syn. but i'm sticking to the Mobil1

MOBIL ALL THE WAY !

[4carspeedin]

Mobil...

[ronsin1]

I have never used Castrrol Syn so I cah comment on it but I can say that Mobil1 works great as compared to Quakastate syn

[Sanctifier]

6 of one... half dozen of the other. No real difference.
I use Mobil 1 in the Evo... NP Ultra in 4wd GSR (4G93T) and wife's Galant VRG (1.8 GDI).
A synthetic oil is only of benefit for certain applications under severe conditions.

BTW for any freshly rebuilt engine, use a mineral oil for the first 1500 miles... and change it TWICE (filter too)... first at 15-20 miles then again at 1500 miles... a synthetic oil is NOT recommended during the "break-in" period.

My $0.02¢

^^how good are the NP oils? Also....whats the rationale about using the mineral oils during the break in period? THat in the link there?

I thought the synthetic oils were always better na....except costwise....never investigated the cost of the syn oils either

[pimptacular]

using the castrol and works good..

but np oils might not be the best on the market but it has to be up to a certain standard and quality to actually be on the market

mobil...

[Sanctifier]

...np oils might not be the best on the market...

What makes NP oil inferior to imported mineral brands?

[Dave]

and let me say this again
all of the L28's(12secs and lower) from laro's garage run np ultra and NONE has ever had an oil related failure

[D_bodyguard]

Go mobil beyotch.... MOBIL!!!!!!!

[bushwakka]

...np oils might not be the best on the market...

What makes NP oil inferior to imported mineral brands?

prolly the fact that is made in trinidad....and since when anything made in trinidad any good?

[eliteauto]

NP Ultra is a very good oil, most ppl are simply brand whores

[Sanctifier]

...np oils might not be the best on the market...

What makes NP oil inferior to imported mineral brands?

... No explanation given yet, padna. Only wild rumour and uninformed gossip.
Do you have any specific empirical data to support that claim?

Click on the link I posted earlier... Research Reports detailed there...
You'll see that there is really no difference in the vast majority of brands being sold out there. Each mineral brand is just as good as another... and the same goes for the synthetics.

Their $0.02¢...

[cacasplat3]

np is a good oil........but i still wont use it, for one reason........there are too many things in np's refineries that doh really impress me

on the other hand.....most foreign oils, like Sanctifier said, are not that different from each other, most get their raw materials from one or two different companies, and he refining process may be a little different, or they may have different additives.......the additives are what usually set them apart IMO, like GTX for eg. has really good anti-sludge properties when compared to other brands of mineral oil

[ziig]

NP oil is great for the price...........I was sponsored by NP for 3 yrs..rana rx7 at 9800 rpm all day and nver had any issues....................

We went to RP later on and found very little wear difference if any.......
