Engine oil Shell or OEM Honda

something you might consider is switching to Shell Rotella T6 5w-40.

you can find many testimonies to the benefits of using T6.

My 1.8t is currently filled with Rotella T6 and I swear its eating less oil now (or maybe I'm getting better with my heavy foot)

I always buy engine oil from Lotus (Tesco). Shell Helix especially on sale.

The same oil goes into all GDI engines at my dealer, which is Shell Helix Ultra SP 0W-20. This is a super expensive, latest spec oil. Oil changes with this oil are done at 9320 miles if turbocharged and 18 640 miles if naturally aspirated.

I have a buddy that used the Shell Rotella diesel oil that is dirt cheap for his 2009 r1.

I'm at 365,000 km and switched to Shell Rotella T6 probably 30-40k ago. Oil consumption was at last halved - the detergents in that oil really help clean up deposits in the rings, or so I'm told.

Quality synthetic oils provide the lowest oil temps, longest running life and superior lubrication. I use Shell Rotella T5 10W-40 for Texas climate.

I've used T6 in my MK4 BEW for 5 years now. Regular changes, no issues at all, and at 1/3, the cost of 'suggested' brand.

Personally I rock she’ll rotella 15w40 in the summer and 5w40 in the winter to aid in cold starting. Seems to work pretty good

Shell helix has been fine for me
