I would cut open the suspect filter and see if the inside looks normal. I would not rule out a counterfeit product. Seems like the leak occurred during a 500 mile window, which seems odd for a gasket being at fault.

Great analysis and article. I wish you would add some 4 cylinder engines. How are the universal averages given by the labs derived and how best to use them?

Were the two bulk oil purchases on the same date? I wonder if moly is subject to settling out or quality control is lacking at Mobil.

Found this article on fuel and SD 85 octane. http://www.ethanolproducer.com/articles/8858/octane-whats-in-your-fuel I believe I filled with 85 octane at Trail's in Albert Lea, MN which tanked my MPG.

Originally Posted By: Artem Yes, every fill up. I didn't notice much change besides the minor fluctuations from fill up to fill up due to changes in driving conditions. I'd still get 38-40mpg on all highway trips with cruise control set at 76mph with the 5w30 oil or 0w20. I also write down...

My issue with filter pleats becoming wavy is the pleats appear collapsed so effectively taking some surface area out of filtration. I also have examples (P1 with 10k) where the wavy pleat junction with the end cap adhesive starts to look torn, not yet a hole but certainly compromised. I also...

Any thoughts on why Yamaha favors auto grades SG or higher non energy conserving II and no diesel spec CD or higher? This is stated under caution about clutch slippage in the periodic maintenance and minor repair section of manual.

I found the VRSC 2012 manual online and it calls for up to CJ-4. Your oil choice is best determined by miles per season. If it is <4k HDEO 15W40 is fine, if going 8k-10k than M1 or AO 20W50. I cannot see paying per qt what is per gallon. HDEO is still very high HTHS, and REVO shouldn't see...

sorry I posted on the wrong thread.

Anyone using a HDEO in a shared sump motorcycle? The VRSC manual recommends "oil certified for diesel engines", although not sure this applies to the CI-4, CI-4+, or CJ-4. The manual says CF-4, CG-4, CH-4. The CJ-4 oils were bottom rated in the TDR57 issue turbodieselregister.com, lower calcium...

Originally Posted By: LeakySeals Although the aluminum appears higher when compared to UOA's of similar engines, what makes your sample different from them is makeup oil. None.

I am curious what GM TEC would do to the UOA. I had searched other Civic UOA's and the Si and Al levels appear somewhat higher than normal. It may be due to dusty conditions from road construction during the OCI where pavement was removed. I assumed the filters could handle it.

The Regane bottles at Big Lots are the older larger bottle that is clear, and the contents is amber. Dark sounds bad or counterfeit.

I checked my gas record and this OCI did have a long trip with big highway days, total trip was ~2.5k. Explain the longer MM interval. I also ran a Gumout TFS cleaner (PEA) prior to this change. Does this add any particular contaminants?

The OCI via MM I would say averages 7500. I wonder if the duration was revised on the new model.
