Hello All:
I'm just curious. I'm sure that this topic has been discussed previously, but as many of you have said, the search function just stinks. Are there any positives or negatives running a high mileage oil in older cars without leaks or excessive oil usage? Here is a quick rundown of the cars, the maintenance and condition:
1. '03 Accord - 2.4 litre - 133,000 miles - Usually use PP 5w-20 (I'm running Peak synthetic 5w-20 - got it on sale for 1.95 a quart) with Pureone filter - sticking with recommended 5 month/5000 mile OCI - mixed driving. No leaks, no usage, all original seals.
2. '02 CR-V - same engine - 119,000 miles - Usually QS green bottle 5w-20 with Puro classic filter - same OCI as above - same condition.
3. '95 Mercury GM - 152,600 - new rear main bearing seal - slight seapage around valve cover - no big deal - very little consumption with new PCV valve valve stem seals appear to be OK - Currently using Valvoline Nextgen 5w-30 (FAR) but will switch to QS Green 5w-30 (got some on sale at Menards) after stash is finished - Puro classic filter but have just purchased some Motorcrafts on sale.
All vehicles impecably maintained - driven conservatively. No sludge or varnish - clean.
I think that I know the answer; there is probably no need to switch. Anyhow, are there any experiences/opinions? Thanks.
