This has already been resolved... here the normal diesel is added 12% biodiesel, a small part from reused frying oils and most produced from direct sources according to the region. North: palm (dendê) and babassu; South, Southeast and Midwest: soybeans, sunflowers and peanuts; Northeast: castor...

Around here we use this oil as biodiesel, produced after being used in frying. Much cheaper, less polluting and with the same efficiency as regular diesel.

I was wrong with regard to the cost of producing synthetics... in fact they are produced from additional processes to obtain so-called mineral oils (obtained in the first stratification of crude oil), so they add more value to their production and consequently higher final cost of the product. A...

I partially agree with you and would like more information on making a synthetic... but as far as I know semi-synthetics are just a mixture of two different compounds, one mineral and one synthetic + additives. When you talk about benefits, what exactly are you referring to? Of course it's not...

Well, I see this as a standard test for everyone... if the test was not satisfactory the oil manufacturers themselves would make a fair complaint or denunciation. I don't know the 3 ball test and I don't even have a way to analyze ash content... do you? Tell us how. Comparing the evolution of...

It depends on where you look for the information... if you look with vendors (or their media), the chances of being misled is great. Believing in "magnetic molecular", "XPTO formula", "high tech", etc... if everything were true, it would have received a higher rating...

In fact there is a lot of confusion, but I wouldn't say that... There are only two oil bases: mineral and synthetic The mineral is 100% petroleum-derived, with additives Semi-synthetic is a mix of mineral + synthetic (created in laboratory), with additives The synthetic is 100% synthetic...

OK, go ahead... but I don't think this contributes anything to anyone looking for help or an opinion about oil... But wouldn't it be better to visit them? I guarantee you that the adrenaline would be much much much higher... and you can even change the oil...:sneaky:

My friends, are you joking or off topic... An oil must not be used for marketing media, labels or personal prints. Oils are manufactured and classified by worldwide accreditation bodies and when stamped with a classification (SAE, API, ISO, ILSAC...), it is because they have fulfilled a...

Oops! My English is not very good, but I don't remember where I left the impression that I'm a fan of some type of oil... I passed on my knowledge about it, reinforcing that the best oil is the one indicated by the machine manufacturer, always. Tell me where I left that impression.

OK, there is a certain logic to this, especially if the oil indicated in the manufacturer's manual contains mineral and synthetic oils or if you use a synthetic oil on an older engine, even if it has similar viscosity. It turns out that synthetic oils are less viscous (compared to minerals), and...

Unfortunately, oil is not a question of love or hate, it is a technical question that even transcends empirical evaluations without its own instruments... and just like cigarettes, the inappropriate use of oil does not cause immediate harm, but shortens life useful or the performance of any...

Sorry, but there is a misconception here... Every oil undergoes a change in viscosity due to heat, that is, the higher the heat, the lower its viscosity... the graph below demonstrates this and more... Credits: https://www.kewengineering.co.uk/Auto_oils/oil_viscosity_explained.htm On the...

No...SAE is an old world society and with strong accreditation, 99.99% of oil manufacturers carry their certificate. The letter W (in the SAE specification) is indicative of oils for negative temperature ranges in °C, partial or total. I searched for 30W oils and I only found one from West...

Me too... it was just to reinforce the importance of the letter "W" in the SAE classification, but it doesn't mean that it didn't exist, doesn't exist or that it won't be created in the future... it's just a question of market or industry needs. For example: why have SAE 0W30, SAE 5W30, SAE...

I know you know, but if you ask at a store: SAE 30W - monoviscous oil for winter (cold weather) SAE 30 - normal monoviscous oil, positive temperatures (majority) SAE 30W30 - multi-viscous oil for winter and summer There are 3 oils with the same viscosity, but they work in different...

Well, the letter "W" in the SAE classification lends itself more to winter oils... could it be that you didn't want to say SAE 40?(without the W)

SAE 40W!!! If there is, it's winter oil... it'll fry at 100°F

I don't understand... what burns faster? Engine or oil?
