What a car. Hopefully numbers will be better after some more regular driving.

@Artem that's the hope atleast, to get their oil with the best protection. @Averroes looks like the big bump in moly helped Valvoline meet the new API SP spec; I guess it would depend on what the euro specs require! @Duffyjr I wonder that too sometimes, if there are other important additives...

Even though I'm not interested in extended oil intervals, I am interested in the best wear protection. The extended protection oil claims to have better wear protection than the Max Life full synthetic I was using before, while only costing $1 more per oil change. Not sure if there is any actual...

Yeah, NP. I was curious, and I figured other people were curious about Valvoline's new Extended Protection oil. I try posting in plain text because I see a lot of old threads with broken image links. But since this image was an attachment rather than a link, it should be okay in the long run...

Hello Everyone, Here is a UOA from a 2006 Nissan Sentra SE-R Spec V with 181k miles. Has 2.5 qr25de engine. Oil is Valvoline extended protection, 5w30 with 4k miles. No additives, for those wondering about the moly count. 12/6 is Valvoline maxlife full synthetic 5w30 api sp, 5/29 is valvoline...

I use oil filters all over the place. The one I used last was a Wix filter (99% filtration at 20-ish microns) sometimes I use the super tech filters because they are so cheap and still filter 30 microns at 99%.

Hi everyone, an update. I just changed my oil the other day, but I only saw one large flake in the oil. Also cut open the oil filter and it looked clean inside. Photo attached of the drain pan, centered around the flake.

Have multiple oil analyses here: https://bobistheoilguy.com/forums/threads/2006-sentra-spec-v-168k-3-8k-uoa-fuel-additive.335601/ Thanks for all the responses so far everyone, indeed hopefully is not bearing wear.

Valvoline Full Synthetic Maxlife was advertised as having the best protection according to Valvoline, even better than Modern Engine oil. But since this new Extended Protection came out, it is now being advertised as providing the best protection.

Hi all, sorry for the confusion, I'll hope to clear it up. I acquired the car used with 101k miles. It currently has 178k miles, however as far as I can remember those flakes have been present since I've been doing oil changes on it, so it's been this way for at least 50k miles. I haven't added...

Hi everyone, I've had some very thin, shiny, copper colored flakes in my engine oil for the past 50 or 60 thousand miles. Internet consensus from a quick google shows this might be from bearing wear (engine: 2006 QR25DE), and the engine is ready to explode at any time, but as mentioned before...

Might be a marketing response to the Valvoline high-mileage 150k oil.

Hi, I’m the poster of the Sentra UOA with Valvoline Maxlife Full synthetic SN, SN plus, and SP. The SN/SN plus formulation had 61 ppm moly in my oil test. PQIA confirms that both the SN and SN plus maxlife full synthetic have around 65 ppm moly. PQIA did not test the SP formulation yet, but my...

@OVERKILL @kschachn @demarpaint I figure that RAT and other one off film strength testers don't fully simulate real engine conditions, but it's the only point of lubricity I know to compare them by. I do wish that RAT would publish his methodology, but RAT refuses for some reason. Wouldn't a...

This 4.7 engine is fantastic.
