I sent an email to Denso regarding their oil filters. It said: With your Denso oil filters, what is the contaminant particle size (in microns) and the filter’s efficiency percentage? Here is the reply: Can someone tell me if my question was answered here?

You own a brand new 6.4 Hemi in a Charger. You daily drive it but it sees high rpm/load daily. There are days in the winter it will start in temps as low as the teens but spends its nights in a garage no lower than 60 degrees. Remove warranty from the conversation. What oil do you feed it?

Is this the date code or?

Is there anything about the SRT branded 0W-40 Pennzoil PUP that would keep the HEMI happier than say any other 0W-40/5W-40 including what I am using now which is QS Euro 5W-40?

I no longer have the Mercedes which used my supply of Quaker State Euro 5W-40, any objections to using it in my 392 Scat?

I have gathered opinions on this in the past but it seems opinions are all over the map. The question is at what oil temp would it be considered sufficient to safely add high load and or RPM?

2018 Mercedes GLC. Have been running Pennzoil Platinum Euro L SAE 5W-30 for the last three changes or 14k miles. Average fuel economy stayed at 25.5-25.7 mpg during this time. I recently changed to Valvoline European Vehicle 5W-40 and noticed my fuel mileage has dropped to 24.7 mpg. I thought...

I bought a UPF48R filter assuming a silicon ADB and received what appears to be a Nitrile. I then found photos of both online. Do you know what this filter is supposed to be built with?

You have to chose only one approval to run in all of your vehicles, which approval is that? Approvals which accompany that approval come by default but curious the one approval you would count on the most. Viscosity not a part.

Not mad about the price $15.25/5 qts. at Walmart.com. I went back online a couple hours later to find it sold out.

I have read through many threads on this subject. I am still unsure if this is an acceptable practice. Leaving warranties out of the conversation, is it OK to mix viscosities and or brands of oil. Example: Mix Pennzoil Platinum Euro L 5W-30 with Kirkland Full Synthetic 0W-20. or Mix...

I thought this was interesting. Mercedes recommends many, many different viscosities for the GLC. VISCOSITIES: All TEMPS....0W-30, 0W-40 Above -13 F .5W-30, 5W-40, 5W-50 Above -4 F .10W-30, 10W-40, 10W-50, 10W-60 Above 5 F .15W-30, 15W-40, 15W-50 Above 23 F .20W-40, 20W-50 In contrast, Nissan...

2021 Nissan Titan-VK56DE Asks for 0-20 or 5-30 I believe. SN and GF5. Can Euro blends in 0-40 be used or just the specific recommended?

Just bought two jugs of 5-40 for S & Gs. $23/5qts. Any opinions on this?

Would it be Mobil 0-40 or Castrol 0-40?

I have two oil filters, both identical but the bypass valve psi is 12psi on one and the other is 22psi. The filter that the vehicle calls for recommends the filter with a 22psi bypass valve. Would any harm be done running a 12psi bypass valve? My guess is the 12psi in a 22psi recommendation...
