Just want to start off by saying that I'm a long time reader and first time poster... from all the posts I've read, I know that there are some really knowledgeable people on here and I'm confident that I'll get some of that knowledgeable feedback from you guys...
Since before I started driving, I was already an auto enthusiast, and like my father have always performed all maintenance/modifications to my own vehicles. I consider myself a spirited driver, but at the same time, I try to baby my cars as much as possible, and am meticulous about their maintenance.
I Just Recently hit 100k miles, and decided to have a used oil analysis performed on my 2005 Acura TSX 6 speed manual with a Honda 2.4L (K24). The car doesn't burn a drop of oil, and runs as good if not better than the day I bought it brand new. The car is driven 60% highway and 40% street. When on the highway, I try to use my cruise control whenever possible set to a speed of anywhere between 70-85mph (85mph = 3,500 RPM). I only redline the car maybe twice a week (only in 3rd and 4th gears) when exiting a toll booth
The car does have some modifications, noteworthy to the UOA would be a K&N OEM replacement air filter, and a Hondata reflashed ECU.
Oil changes between 5k – 45k miles were with Castrol Syntec Blend 5w30 and Purolator PureOne filter performed religiously every 5k miles.
Oil Changes between 50k – present have been with Pennzoil Platinum 5w30 and Purolator PureOne filter on an average of every 7.5k miles.
Blackstone’s comments: Lead was slightly high in your Honda’s fist sample, but we wouldn’t get too bent out of shape about it. Our universal averages show typical wear for this type of engine after ~6,700 miles oil use, and since your oil run was longer than that, most wear looks great. Lead is high by just 4 ppm, so we won’t worry unless it goes higher from here. The slightly low viscosity probably isn’t a problem either, since we didn’t find any contamination. The TBN is still good at 3.1 (1.0 is too low) so we’d say this oil can go longer. We bet you could go for 10,000 miles next time.
I guess my concerns are:
-Lead being slightly higher than their universal averages
-Slightly low viscosity (shearing)
Any advice would be greatly appreciated…
