Remote bypass oil filtration

[Ry_Tower]

I often see the Repsol Brand Mineral based oil as advertised. Okay ba ang quality nito? how does it fare against Castrol GTX for diesel engine?

Ok repsol but they are more known for MC's oil.

Looks like perfectly fine oil, a little low in the ZDDP but good moly and boron to make up for that. And at almost 15000kl
on this sample still has enough TBN to go a few thousand more.

But if you have car with sluge issues this would be a bad oil for you since the detergents are so low (calcium) is way below the normal average.

dvldoc, speaking of sludge, is it safe to assume that sludge is from use of low quality oil + low quality filter?

^im also buffled with the sludging issues of the altis

thanks doc! for the quick reply and information you shared, the sample was run on TDI diesel engine, is it safe to use this on gasoline engine? thanks

Folks we have our self a winner, You got it crazy boy, it's the number on reason for sludge, second is other contaminates like coolant. Some engines are just sluge monsters due to a bad design, Toyota's 1997 to 2002 for example.

If you use a low detergent automotive oil then you can expect to have a sludgy engine. If you have a coolant system leak expect the same. That's why it's always best to know what's in your oil, It's good to pull your valve cover from time to time just to check if everthing's good to go.

dvldoc, thanks for you input hehe. cause locally, i have seen dealer maintained toyota cars running on OEM oil filter and OEM toyota fully synthetic oil (Chevron rebranded), OCI of 10,000km, and sludge started to form as early as 30,000km.
however, on our toyota cars, we use Delo engine oils to flush the motor every 30,000km. we use it for 1,000km and then drain it and then back to our oil of preference. currently, we are already using Baldwin filters and Zic oil, with OCI of 8,000km. hope that our motors will not sludge.

Diesel oils will normally offer you much better engine protection than just regular automotive oil. The only thing you need to know is don't run oils with more than 1200ppm zinc or phosphorus. I don't like the low calcium because it can lead to sludge in your engine.

5000klm oil change intervals are a complete waste of money, 8000klm to 10000klm is more inline with 1000's of oil test have shown to be a safe and recommended oil change interval. 12000klm is a normal oil change interval here.
