    Anyone have a vehicle long term to back their OCI?

    I've visited here for years (old SN Speedy1975), loads of great info. People seem to agonize over OCI, oil types, etc, and I'm curious if anyone has a vehicle they've actually owned for say more than 10 years that would back up their OCI and oil choices? When I went to a once a year oil change...

    Effect of leaded fuel on UOA?

    I did some searching but only found a couple older threads on classic cars and a mention or two of a raced Miata that talked about the effect of leaded fuel on UOA. Does anyone have experience with how much of an impact running leaded fuel has? If universal average is 5 (random number) and you...

    Analysis testing long term complete

    I've been running a test on various motor oils in a 1999 Honda Accord that sees a lot of miles. I was curious if one oil was really better than another. I tested each oil for right at 10,000 miles using the same oil filter. The drive was the same with about a 50/50 split of city and highway for...

    99' Honda Accord 2.3L PP 9,777 miles

    I've been running various oils in the Accord beater to see how they fared. This may not be the most scientific test, but it is kinda interesting to see how wear changes with different oils. I started with Castrol GTX 10W30 which did pretty well considering I ran it 10,000 miles...

    Castrol Syntec 5W30 10,203 99' Honda Accord 4cyl

    I've been testing various oil for 10K miles. Last sample was Castrol GTX 10W30. As you can see, in this case I don't think the Syntec is worth the price. I'm now testing Penzoil Platinum 5W30 to compare. 1999 Honda Accord 4cyl 2.3L EX Auto Oil: Castrol Syntec 5W30 Filter: Purolator PureOne...

    2007 Honda Civic 1.8L,Castrol GTX10W30,10 mos,6357

    This one's for all you 2007 later Civic owners out there. Standard Castrol GTX 10W30 dino oil was used until the Honda OCI was at 5%. I've switched over to Penzoil Platinum 5W30 and will run an analysis on that once the OCI is at 1% for comparison. Will probably be a year from now. 2007 Honda...

    2001 Honda Accord 3.0L V6 Oil Specification?

    2001 Accord V6 owner's manual says 5W20 for all weather. My 1999 2.3L 4cyl Accord manual gives ranges of different oils based on temperature. I've been running Castrol GTX 10W30 in the both, but the wear metals are a tad higher in the V6 and I'm wondering if the 10W30 is too thick and I should...

    Castrol GTX10W30 10,330 Miles Accord 2.3L 4Cyl

    This is a daily driver, commuter, car pooler, and general beater. I've decided to use it as a test mule for various oils. I've submitted a couple of analysis on it previously (5K and 8K miles). This time I went 10K on the oil and the filter had 19K on it as I did not change it last oil change...

    2009 Challenger RT Oil Recommendation?

    Just bought a 2009 Challenger RT. It has the 5.7L Hemi V8 engine and 6 Speed Manual transmission. Book says 5W20 oil, but keeps focusing on MDS as the reason for that oil. My car is a 6 speed and does not have MDS (cylinder shut off for gas mileage feature). I use Castrol GTX 10W30 in all my...

    Castrol GTX 10W30 8794 Miles1999 Honda Accord

    I switched from OAI to Blackstone for this latest test since I like their format of not charging me until the analysis is performed. I will be using Blackstone from here on out. You can search my previous posts to see this same oil analyzed at 5K miles by OAI. Current Analysis 1999 Honda...

    1999 Honda Accord 2.3L 4cyl Oversized Filter?

    I've searched here, as well as several Honda Accord forums AND Google and am having trouble finding information on the availability of an oversized oil filter for my 1999 Honda Accord 2.3L 4cyl.

    1999 Honda Accord 2.3L 4cyl using oil?

    I'm about to do my first UOA on this vehicle that I purchased as a daily driver. It's an auto with 95,000 miles on it. I've ran Castrol GTX 10W30 for the past 20K miles at 5K mile OCI. Prepping for the UOA I noticed it seems to be using a bit of oil. I'd guess a quart in the 5K miles. I'm...
