Used oil analysis of Petron 5w30 synthetic oil

[jackaroo]

garyq,
Magna asia is near the mandaluyong rotunda, Call them at 534 1268. A case has 6L.

ner,
Is that 7600km total mileage on the Xwind? If so, then you can change to full synth at 8k km or 10k km. If Isuzu used their IGMO sae40 oil, then Petron's 5w30 synth is a huge improvement on your present oil. If you don't want to spend on synth then use Mobil delvac MX 15w40- again better than isuzu's monograde for a new vehicle. But use orig isuzu oil filters to keep your warranty!

roydok,
Thanks. There's a Petron sales outlet along the hway in Los Banos, think it's a half km before the UPLB turn-off going towards Bae. I've visited the place before and they had 5w30 in stock.

RedHorse,
I was using a Vic air filter but orig isuzu oil filters during service period. Think you can extend to 7k km safely if on Vic replacement oil filters. I plan to replace our secondary(sub) oil filter after 10k km- but only isuzu has this type of filter.

Jackaroo,
Thanks, Bro for the info. Next PMS ko, I'll use Petron All terrain instead of Turbo XP. I'm satisfied with the performance of Turbo XP kaso lang nakakabutas ng bulsa. With petron all terrain, I'll get the same performance at half the price....:o:o:o

mangyan,
Welcome. Although Petron has labelled its oil as a 5w30, the specs will pass even as a 10w30 oil. Some dealers may question the use of too thin an oil when they see 5w30 on the label.

jackaroo:::very informative. thanks for the info.

Great infro jackaroo!!!

Question lang.... at what temperature does the "W" take effect. All i know is that this is the viscosity of the oil for "winter". I was thinking since wala naman tayong winter sa pinas, di masyadong critical tong number na ito.

REVX-All Terrain na ako next oil change! Its time to treat my Paj with a synth oil! :mrgreen:

:D

afrasay,
welcome.

pajerokid,
True, the "w" is the winter rating but it also shows how low a viscosity it carries. In our tropical temperature, it helps by circulating the thin oil immediately after start up.
If you were using a mineral oil with a 5w30 rating in our temperature, there is a higher probability that it will break down and solidify thus leading to engine damage. That's why some manuals don't recommend the use of such a rating in hot climates or high speed runs.
But as the test shows, this synth oil can withstand our heat and turbos!

Okidoki! :wink:

jackaroo,

This is a typical UOA result by Blackstone (USA), and this comes from a 1983 MB 300D Turbo:

Aside from the 5 parameters that the Petron lab tested, is the lab able to come up with any of the above? From my readings, it appears that Iron, Chromium, Lead, and other heavy metals concentration in the oil sample will give an indication of wear in the engine, and definitely this info is very important for our appreciation.
