The oil was drained early due to a scary report from a 1NZ-FE Corolla with its TBN reaching 4.0 at 5,000km. Seems like the fears are unfounded. Should have brought the oil to 10k. I clock predomnantly highway miles as opposed to very short 5km trips.

Previous thread on the RP 5W20 is here:

Well there are a couple of factors to consider. The engine is still breaking in so this skews the comparison between the Redline and RP. Its odd that during the RL test even with fuel dilution it went from a 20 wt to a 30 wt with only 3000 miles. But anyway..I see no need for a 40 wt.

What happened to your Si number?

Oops! Let me update it.

Wear looks fairly consistent trendwise. The 5w40 seems to give slightly lower lead wear. The oil did shear to a 30wt though. Did this oil see any high speed driving in Malaysia? The silicon doesnt seem to be going down any further, so I would assume the gaskets have stopped leaching silicone. Are you still using the OEM air filter? If it is silicon (dirt), it seems just a tad elevated. A new air filter might be able to bring the Si down to a single digit, and consequently the other wear elements will go down. I change mine every 10k cos SG air is kinda dirty and the filter turns black within 10k.

No highspeed runs up north. Could have explained the lower wear. Yes using the OE paper filter and it was changed. Removed my resonator to help the engine breathe better. Yes I did notice my filter turning black by 10k. The high fuel dilution in RP then could be due to the poor engine/fuel management system. Was really running very rich for that 2+ hr high speed run.

Considering a change to ITG or Unifilter foam filters but they look pricey and I don't like spending time washing filters.

Hi Ken4

How do you tell that the oil has sheared down to a 30wt? Please enlighten me.


Thanks
