I will start by saying I'm not certain the correct sub forum to post this in because this is neither a used oil analysis or a maintenance item because I haven't performed it yet. As some of you may be aware I have tried a variety of different oils at different intervals in my 2004 Lexus ES 330. The Lexus will be due for another oil change within a few weeks and I was curious if there are any oil's currently in my stash that people would like to see a used oil analysis on. Here is the list to choose from listed in the first column and the second portion would be the interval I would use that oil for.
MILESYN SXR 5w30 / 5000
Castrol Edge Black Bottle 10w30 / 5000
Castrol Edge Euro 0w40 / 5000 sample perhaps run to 10,000
M1 ESP 0w30 / 5000
M1 EP 10w30 / 10000
M1 15w50 / 5000
Napa Synthetic 5w30 / 5000
Rotella T4 CK-4 10w30 / 5000
Quaker State clear bottle Advanced Synthetic 10w30 / 5000
Picture of QS for reference
I have a few others in the stash but they'll likely be used for customer oil changes or in other vehicles I own.
Yes some of the intervals are short at 5,000 miles and the engine has been proven to be easy on oil and could probably go 10k on almost all of the oils listed but 5k is an easy mark for me as it lines up with the maintenance reminder and tire rotation schedule I'm using as well as even 5/10k intervals on the odometer which is why I'm not likely to switch to a 7500 mile interval.
Curious to see what you guys would like to see run next!
