I would be surprised if Toyota made a conventional oil, as usually all customer oil these days even if dino, is blended due to line costs

 

Yeah I guess I shouldve said does toyota sell branded 5w30 conventional. I would assume no auto manufacturer actually makes their own oil even if it has their OEM label on it. "OEM MB genuine oil" is in fact liquimolly if I am not mistaken, for example.

 

Pretty sure TGMO is just some white labeled Mobil1, maybe some different additives vs the shelf version

 

A search shows Mobil makes most of the "Toyota" grades of oil.

 

yes on the oil analysis, already on board a while ago.
Yes, I work deeply well beyond oil changes on cars.
Asked about metal flakes on filter pleats because I wanted to know what you guys see on yours.
To be candid though, I haven’t really been checking oil filters closely until recently with the LX600 engine recall fiasco.

Metal flakes Circled in photos below, dark brown filter is old, possibly unchanged filter (6k-9k?). Light brown filter is 2.5K

 

I just did my 6-month oil change (only used about 800 miles in that 6 months, thanks to the wintertime inactivity). When you guys do your oil change, do you fill the oil up to the Full marker or right in the middle between low and full ? i used to always put it straight in the middle, but then my dealer told me i should keep it to the full line just in case. In case of what you ask? well in case it burn some oil, if I continuously bounce it off the rev limiter (i rarely, if ever, do that). Logic seems sound.

 

I do mine just shy of full so when oil expands should be just right..sure the engineers have figured this out when deciding where to put full line on stick.

 

Would that be like the guy who under inflates his tires bc he knows driving will increase the pressure up to the door plate value?

 

I fill mine to the top dot

 

Sorry to say the liquid will not expand. Fill it to the full mark. Run it for 10 miles and recheck. From someone who's done this for 60 years.

motor oil expands 5-8% when hot..Google it my friend.

 

Yes your google search will reveal a possible small expansion bases on wide temperature variance. Not enough for me to be too concerned about. Many more items may cause problems. Such as dirty oil funnels, not fully cleaning oil filter housings, over filling oil amounts, mixing grades of oil, over tightening filters or drain plugs. I have always contributed the slightly higher oil change to the oil being more "fluid" when hot and draining quicker and more completely into the oil pan resulting in a slight change. That is why I also do the level check after a 10 mile run Thanks for the specific research.
