Used oil analysis of Petron 5w30 synthetic oil

**jackaroo** · April 2nd, 2003 09:27 PM

Used Petron 5w30 all terrain oil sample from 3.0TD trooper (mileage of 38k kms) after 5000kms use, tested last 11 march 2003.
Test results:
KV at 40C 63.12
KV at 100C 10.47
Visc index 155
TBN, mg 14.1
Pentane insolubles,% 0.09

1) Viscosity decreased slightly from 74.3 at 40C and 12.06 at 100C when new, still within a 5w30/ 10w30 spec. Visc index still high as expected from a full synth oil.
2) TBN- from 16 new- only decreased to 14.1 which means high retention of detergent/dispersant additives so better protection from engine wear and bearing corrosion. Normal oils may see TBN halved after 5k kms.
3) Pentane insolubles measure dirt, dust, metals in oil that wasn't trapped by oil filter. Indicates quality/ life of oil and air filters, engine wear. A safe/ max limit of 2.0% so result of 0.09% is a long way off.

Based on these results, IMO, the oil is good for another 5000 kms use but may opt to change oil after 7k km. Looks like a good oil for the 3.0TD trooper! :D

buknoy2002,
Petron's all terrain is only rated for diesel, they have ultron race 5w40 synth for gas. If havoline energy is their 5w30, accrdg to caltex, this is not rated for diesels.

mangyan,
Mitsu's turbo XP by amalie oil has a wider visc range, think 5w50 but haven't seen the product specs on this oil. If priced at P500/L then would rather use mobil delvac 1 5w40 with proven specs.

garyq,
Welcome, hope info helps. The oil is available from Petron sales centers at P245/L like Magna Asia along Boni ave in Manda.
You can extend drain interval to 10k km but suggest you replace oil filter after 5k km to keep dirt in check. Or replace both oil and filter after 7k km since this oil is relatively inexpensive for a full synth.:wink:

Jackaroo,

Perfect timing again :lol:

Although less than 5k pa lang ang tinakbo since Jan, might as well change oil, considering na daily driver ito sa school. Traffic pa naman doon.

By the way, my mechanic friend, pointed to rust particles found sa fuel filter (replacement) sa fuego. So, back to orig isuzu on fuel filter, and stay on replacement filters for Air and Oil.

:evil: Kaya lang, sabay ang Trooper at Fuego sa maintenance sked.
