I've posted a few threads about this car in the last couple of months and was rewarded with good advice.. This posting is, in some ways repetitive, but more a continuation after making changes or cleaning up some potential problem areas.
My daughter's '98 accord has 188,700 and an irritating piston slap along with a thirst for oil... 1qt +/- every 1,000 miles which started at around 175k miles. Not leaking... No plumes out the exhaust. Oil is just consumed. Performed compression test earlier this year and the numbers were very good across the board - although I can't remember exactly what they were... 190, I think?
Until this last OC, car had a steady diet of Mobil 1 5W-30 and I changed every 5k. For some reason which I can recall, I decided that a 3k OCI might be good move going forward.
Car Specs:
1. Bought the car in '09 with 150k miles. Been running very well
2. Routinely replace the PCV every other change
3. Clean engine (no sludge)...
4. Kreen run last 500 miles in sump before OC with Seafoam run thru intake
5. Last oil change at 188,100 with Pennzoil 5W-20 and MoS2 and Fram Tough Guard filter
6. 99% use will be short hops to work which is less than 2 miles up an down Hilly terrain. Maybe twice per month a 200 mile r/t run.
Some questions:
- is it true that it takes some time for the effects of HM oil to make themselves apparent? My hope is a HM oil will mitigate the oil loss and I'm wondering at what point I can expect to see the results
- I called it piston slap above but am not 100% certain that's appropriate. Valves have been adjusted and it still makes noise so I'm inclined to rule out a valve tick. Might a HM oil have any impact on valve train noise or piston slap? This noise won't stop after car has warmed up
- I went with the 5W-20 this OC thinking it might offset the fact that the car rarely gets a chance to fully heat up. Was that a good or bad idea?
- I picked up a jug of Valvoline MaxLife (red bottle) 5W-30 as the price was great at Walmart: $12 after coupon. Easily returned if that is a bad pick
- of the HM oils, does any specific brand stand out as a clear "winner"? Given the car's usage above, might one be a better candidate than another?
- is it a bad idea to change from one HM oil to another before giving them time to work? In other words, run a HM oil 2 or 3 cycles before changing...
I've stated before in previous threads that I enjoy working on cars but after an entire summer with very little accomplished toward stopping the oil loss or deadening the noise, I'm getting tired
Any/All input is appreciated
