Is it really stated anywhere as a rule na dapat fully synth lang every 10k ang OCI? What is the difference pala of multigrade sa mineral? Kasi yung delo 400 multigrade nakalagay. Mineral din ba yun? There are fellow tsikoteers kasi na nagsasabi and i believe based on experience na delo 400 plus a good filter like baldwin can do 10k. I dont want to start a debate here. I just want clarification and what is best for my engine. All of you are of great help for someone like me and i am very thankful. I am learning a lot.
Right now, I have a low mileage L300 about 19K mileage now. It has been on BD28 and Delo 400 since 10K. The driver who belongs to the old school of thinking (and practices), tells me that he felt from the oil dipstick that the oil is "sunog" (* only 7.5K mileage) already. But with the way Baldwin BD28 (1,000/pc) and Delo 400 (265/liter * X liters) costs right now, this somehow subconsciously tempted me into extending the OCI to 10K to even a bit more just to get the most of the cost. But come 20K, definitely need to change already despite some people posting that it can be extended all the way to 12K per OCI.
Bosch Om 036 *350, I can buy almost 3 pcs of this for 1 pc of BD28). Rimula R3X (by the 20 li pail) is really inexpensive at only 110/li (if i'm not mistaken). So you see why I rather do frequent oil change and fact that I only use regular euro 2 Shell Fuel Save Diesel.
I don't understand this question.
Minerals oil comes in multigrade meaning it has two viscosity ratings which allows it to be used in cold and hot weather. Monograde only has only viscosity rating which is applicable or suitable to hot/warm engine conditions.
Mineral Vs syn. Both are manufactured from crude oil. Only Group IV or PAO based syn like AMSoil (forgot the series) and Mobil Extended Performace are fully man made synthetic made in the labs. Other fully syn like the reg. Mobil 1 are made from Group 3 (meaning it has more processing, distilling, purification etc... ) to make its molecules consistent and etc. as required on extreme conditions. Reg. mineral belong to Group 1 or 2, meaning they much less processing, refining, vs. Group 3.
Delo 400 is mineral oil that has supposed more additives and process to make it perform like synthetic hence its called synthetic blend.

Oil quality might look good on papers but actual oil performance on engnie might difffer.
*number001: that was very enlightening sir. thank you for sharing. i appreciate it. i learned something again.![]()
May napost na ba about Petron RevX All Terrain 5W40 kung pwede and maganda ang specs for gas engines?

Co Wikipedia:
Total base number (TBN) is a measure of a lubricant's reserve alkalinity. It is measured in milligrams of potassium hydroxide per gram (mg KOH/g).[citation needed]
TBN determines how effective the control of acids formed will be during the combustion process. The higher the TBN, the more effective it is in suspending wear-causing contaminants and reducing the corrosive effects of acids over an extended period of time. The associated measurement ASTM D2896 and ASTM D4739-06 generally range from 6-80mg KOH/g in modern lubricants, 7-10mg for general automotive use and 10-15 for Diesel operations.
So basically the higher the TBN the longer you can run it in your vehicle. So if you start with a whopping 16, you can run it for a long long time. I saw a used oil analysis, he used this oil on his trooper. ran it for 5,000 then had the oil tested, it registered TBN 14, that was after 5,000 KM, VIC pa gamit nyan oil filter, just imagine kung baldwin pa ginamit nya.
sir when you say it registered 14TBN using vic after 5k meaning malinis pa yung oil? sa tingin mo ba sir kung ganun it can last 10k OCI using bosch oil filter, meaning after 10k na rin palit ng filter? hehehe sorry kung pang dummy yung tanong trying to learn about this things...
Sirs, tama ba itong logic?
E.G. If I use a very good oil and a poor filter. Oil could last 10K but filter only 3K, pwede ba ung filter lang palitan every 3k? To my understanding, kailangan palitan both oil and filter kasi every OCI.
using poor filter with good oil defeats the purpose of using good oil. If you use bad filter, particles smaller than 30 microns gets recirculated back to the engine causing greater damage in the long run. Tbn will be still be high for good oil when you do oil analysis, but particle count for wear metals in the oil would probably also increase. Bosch filters are good over the counter filters as good if not better than oem but not up to baldwin or fleetguard stardards. Mura lang naman sya so changing it every 5k is extra safeguard. Kung walang makuhang baldwin yan gamit ko
Wala dapat tatapon na langis pag tinangal mo filter (konti cguro galing sa cavity between filter and filter housing base). Kasi nasa crankcase ang oil mo. Kung wala o non functioning ang anti drain back valve ng filter mo tatapon yung langis na nasa loob ng filter habang tinatangal mo sya gaya ng sa VIC filter.
