Southpark2000 Neutral Newbie January 11, 2006 Share January 11, 2006 What is worrying is not the oil viscosity for us Singapore users. It is the damn air! All the SG users report double digit silicon numbers. That means sand/clay whatever in the air. All the SG users are using stock paper filters. If it is already so bad with stock filters which do the best filtration, you can imagine the people with the K&N and Hurricane. Prof Genie, Any thots wat's up wif the air? I thot we green green city?! The next qn then is whether our fellow johorians or m'sian's UOA show same situation? ↡ Advertisement Link to post Share on other sites More sharing options...
Genie47 1st Gear January 11, 2006 Share January 11, 2006 That I dunno. All our Si are double digit. BTW, go to UOA forum. cxxxxxe TR 5W40 SL UOA is out! Same guy that did for the Corolla when the first SJ report before mine came out (on BITOG as dm). This time on a 03 Sunny. Results are but even the oxidation and nitration are . Not bad for a cheap oil eh? I think next time for more people go sapu all when sales come. Shows that cheap oil can be good too. Link to post Share on other sites More sharing options...
Cyberet Neutral Newbie January 11, 2006 Share January 11, 2006 (edited) stock paper filter.. Si 8x more with paper, than previously K&N, even though the previous UOA was only 5k km + K&N. lead went down i think, previous was 18 for 4.5k run, now its 23 for a 8k run Edited January 11, 2006 by Cyberet Link to post Share on other sites More sharing options...

Genie47 1st Gear January 11, 2006 Share January 11, 2006 Eh? Reorganize the report to the style of dm or my latest with the Conoco Hydroclear. At least can give you some trend analysis. My Citgo going to be send already. The SS7k 5W20 in the engine already. FC not much different from the Citgo. Maybe because the Citgo 10W30 sheared to 10W20 the moment I poured it in.

Southpark2000 Neutral Newbie January 11, 2006 Share January 11, 2006 Well thanks to you in patiently educating all of us , we have "graduated" to recognising that price is not a reflection of the effectiveness in the case of engine oils in SG!!! ....at least I have, and I meant it as a compliment. My Jazz seems to like the 10w30 Schaeffers despite it being a blend (v. good blend). I experienced no increased noise (except the occasional high speed revs), smooth, more torquey, etc....no hav UOA though. FC has definitely increased by approx. 1-1.5 km/l...based on onboard FC meter due to light wt oil I guess. And it's affordable oil!!!

Cyberet Neutral Newbie January 11, 2006 Share January 11, 2006 yeah, 8x more, after i'm done with the ARX rinse, think i'll try next RP 5w20 run with my K&N again, and see if Si figures goes down again. 2.7L sump 8k km, RP + LC.. i can't imagine what would happen if i didn't use LC Link to post Share on other sites More sharing options...
Genie47 1st Gear January 12, 2006 Share January 12, 2006 (edited) Not much difference in the lead wear between 5W40 and 5W20. Could be the Si. Nitration and sulfation not much difference so can say it is our conditions. There is some difference in the oxidation though. Thin oil seems to oxidize faster. Oh wait, TBN down to 1.5, that figures. Edited January 12, 2006 by Genie47 Link to post Share on other sites More sharing options...

Genie47 1st Gear January 12, 2006 Share January 12, 2006 Don't have 10W20 lah.Only 10W30. Nobody has sent it for test yet. I think most think the cost is prohibitive. Link to post Share on other sites More sharing options...

Lead wear is actually lower at 2.85ppm per 1000km vs 3.99ppm per 1000km but the oil is pretty shot at TBN 1.5 Link to post Share on other sites More sharing options...
Genie47 1st Gear January 12, 2006 Share January 12, 2006 Wear per 1000km is not indicative of the performance. Wear fluctuates actually so you cannot pinpoint it. Just be glad he drained it. Link to post Share on other sites More sharing options...
Trex101 3rd Gear January 12, 2006 Share January 12, 2006 (edited) Yah quite true that engine actually wear more initially then later wear rate taper off. But from the result it really shows that our engine don't give a damn what we dump in... be it 40wt or 20wt. The wear was pretty comparable with both oil.
