Currently 4500 miles into a planned 6500 mile OCI using Pennzoil 5w-20 conventional. It got me thinking about how many others are using 20wt here at BITOG.

If you're using 20wt, what's your planned OCI? Are you planning on an oil analysis (UOA) for your vehicle?
 
7K OCI on 2004 Honda Element from 3500 miles to 66K miles:

Mobil 1 0W-20 or Mobil 1 5W-20, now Pennzoil Platinum 5W-20 all run at 7K intervals. Engine runs great, zero oil consumption.
 
My wife's car has GTX 5w20 in it right now and it just passed over the 3000 mile point. I'm going to change it at 4000 miles, a bit sooner than I originally planned since her thermostat was stuck open for almost the entire winter (and it was a cold last half of winter here too)

I will be changing her car over to Petro Canada 5w20, and will run it for 5000 miles. As always, I will do a UOA (for both the GTX run and the PC run)
 
I am the opposite end of the OCI. I have one vehicle that uses 5w-20, but the oil wieght is not the determining factor. I will be running 3K to 4K OCI's. My engine is a DOHC non-free flowing engine with valve timing regulated via oil pressure. There is risk of sludge or varnish impeding the flow of oil into the little orfice of the timing chain tensioner. With current and future BOGO's of PP, I will be doing 3K OCI's. May be overkill, but it's very affordable overkill. The engine costs between 5 to 8K to replace, why not be safe. However, if a future UOA states otherwise, I will extend OCI's to safe levels.
 
Both my vehicles use 5W-20. The Escape is getting MC 5W-20 and I'm changing it at around 4K mile OCI's. The Accord was getting MC 5W-20 until the last change, when I switched to PP 5W-20. On the MC, I was changing at around 5500 miles (OLM still at around 25-35%). With the PP, I'm going to run it a little longer, maybe to about 7K and assuming OLM around 10-20%.

I did a UOA on the MC from the Honda, but I'm going to wait to do one on the PP until the second change. For the Escape, I'll probably do a UOA at the next change.
 
I've been going 4K-4.5K miles with Pennz 5w20 since 100K on the odometer because most of our trips these days are 3 miles or less with the occasional interstate cruise. I'm still using my Home Depot stash, so it's a very inexpensive oil change.

I've never been an extended mileage interval guy, even when doing 1200-1500 mile weeks for years on end, I only went 6k-7K with M1 5w30. Oil analysis is not a hobby of mine, I live vicariously through others in this regard. I'd rather spend my money on oil and filters.
 
i'm getting ready to bump my 5k oci with RP 5w20 up to 7,500 on my 2.3L mazda. My escape will probably be 7,500mi OCIs with PP once i get to the 5k mark.
 
I'll be pouring Pennzoil conventional 5w20 with 5oz VSOT in about 500 miles. Will run it for 5000 miles and will be getting a uoa done. Right now it has Pennzoil 5w30 dino for 3300 miles and will have a uoa within a month.
 
I have a 6500 mile run of Mobil 1 0W20 from an 04 accord v6 I need to get sent in for anaysis.
 
According to the OLM in my 2006 Honda Odyssey (which specs 5w20), my oil should be good for around 10000 KILOMETRES. I changed out the FF at 7300km and the OLM was at 30%. This was probably 70% highway. Currently at just over 12000KM and the OLM is at 50%. I'm not comfortable leaving the oil in for 10000KM, so I plan to change again at 30% (this is on dino - I plan to switch to synth this oil change, which I may leave in till the OLM tells me to change it).

Last year, after initial 3000 mile OCI of Mobil 1 5w30 in 2001 Taurus 3.0L DOHC V-6, I installed Mobil 1 5W-20 for planned 7K OCI at 63,000 miles.

Engine used no oil for first 4.5K of OCI, but minor consumption issue developed after that. At 6.5K I dumped it for current fill. Still had minor consumption issue for first 1K of current OCI, but that has since been resolved.

Out of curiosity, what engine is this?
 
~9700 miles into a 10K OCI on my '05 Civic with havoline 5W-20 (~29700 unit miles). This'll be my third 10K + UOA run

As long as possible. I've tried it for 5k on my wife's jeep. MC didn't have a good showing ..but I had fuel issues. PP is in now. If it passes the 5k test, then we're on to 6 months (about 9k) ...which I figure is most people's limit.
 
"Out of curiosity, what engine is this?"

It's the Chrysler 2.7L DOHC. Bought the car with 27K and found minor sluding in it. Most of the sludge issues supposely have been resolved with this engine, but may have endured some neglect from the previous owner. I am not a gambler, so I insist on frequent maintanence when an engine type has a history. The high price for replacement is rumored from the fact that rebuilds and junkers are hard to come by.
