Originally Posted By: Swifty As far as the gas mileage difference between the two grades it is minimal. On my second oil change I used 5w/20 and logged my mileage for the entire interval using a fuel app and then averaged it out. Then went to 30 weight for good and logged the mileage for that...

Originally Posted By: steve20 My 05 Accord K24 has 254 K miles on it now. From 0 miles to 101 K, I had been running on Castrol Syntec 5-20 or Syntec Blend 5-20. I took a real good look at the cam thru the oil fill hole, and didn't like what I was seeing on the cam lobe surfaces---way too much...

Originally Posted By: jongies3 Change it for peace of mind, unless he had it parked in a climate controlled garage, that oil's been subjected to all kinds of temperature and humidity changes, all which helps to break it down over time. Assuming it's carbureted you can bet there is some fuel...

Originally Posted By: MolaKule Grease Technology I Grease Technology II hello MolaKule, thanks for great info! As some have mixed oil into mobil-220 grease to get a softer (lower nlgi) grease for their purpose. When oil is mixed with the grease, air bubbles and air pockets are formed. Is...

Originally Posted By: dnewton3 Until wear rates are affected in a trend slope that would indicate wear is escalating to a damaging level, and/or those wear metals came to a condemn-able level, it's not time to OCI. makes sense. Is there any way to determine and measure if the oil (and nothing...

Originally Posted By: UncleDave I think its an awesome filter and run them in my motorhome. It is one of if not "the" finest filters available for a diesel engine. UD Why is this filter only diesel engine specific, does it not work for gasolines?

Originally Posted By: dnewton3 So changing a filter, as you suggest, at 8k miles into a 15k mile OCI, isn't really going to do much of piddly squat, because data shows that the typical oil add-pack is still very viable, out to 15k miles. IOW - the FF filter (or even a BP filter) cannot catch...

Originally Posted By: dnewton3 TRUE: There is more than one means of attaining a sump clean enough that sustains the desired wear rates. Consider two examples: veh A uses normal oils and filters, and OCIs every 10k miles. veh B uses syn oils and BP filters, and OCIs every 25k miles. During the...

Originally Posted By: mightymousetech Basically the same engine as the 06-11 Civic Si, and that car calls for 5W30. Here at Acura, our 5W20 is semi-synth, our 0W20 is full-synth, so here, would be better off using the 0W20. I believe this is a Canadian thing, in the US they use semi-synth 0W20...

Originally Posted By: radu 7000 sounds about right, then see from there. That Duron looks (on paper) like a LL04 5w30 but with a higher TBN and actually a bit cheaper than Mobil ESP 5w30. Why is it LOWER PRICE???? Is base oil quality lower or its promotion prices ? These are important...

Originally Posted By: radu The Duron meets mb 228.51 and some ACEA Es. Any love for PetroCanada? Originally Posted By: radu I can get it easy and at a good price, ~40 USD for 5L. A steep price for simple 7000 oci runs. What oci do you plan with this oil ?

Originally Posted By: TheKracken My prius only needed tires and oil changes. Oh and the OEM breaks lasted until 225k miles with lots of city driving. Wow 225k miles.. that's unbelievable achievement.. how were you so incredibly careful when braking, and what did Toyota dealer say when you...

All in all I would much prefer if sub micron filters are included as a standard feature in today's cars, possibly as a super long life bypass filtration, considering their prices are always going up and this area remains neglected for improvements during last 30 years.
