I'm using the heavy duty dieslel oil T-6 synthetic 5W-40. My now has 299,500 miles and I was trying to see if it would blow less oil than using Mobil 1 synthetic. So far, no difference.Does anyone here use Rotella t5? On bitog, there's some decent uoa's on it with the ep3 civic si using it and other random engines, but I don't know if they wind it out or not. I'm just wondering if you guys think its ok for a stock k20z3? It's a 10w-30 on the thicker side, cst 12 @ 100c.
Thanks on the mileage. I need to buy a replacement motor or Franken build and have it ready when this one pops. It would be fun to work on a motor on a stand. May be work a trans over to to change gear ratios. Car still looks good.Amazing mileage man. I've seen only good UOA's on the t6 also. Just wish they made a 30 weight.
#1 - if it works for you keep doing it. If you are not putting down many miles and not crossing the Arizona desert to dispose of bodies than the 3k miles seems a bit quick.I use Pennzoil Synthetic Ultra 5-30 in my car, with a Pennzoil premium filter ever 3k miles. I know that I can go longer on my oil changes, but I choose not to. I also change my manual transmission fluid every 30k miles instead of the recommended 60k with the newly improved Honda Manual Tranny Fluid. I know that some people choose AmsOil over the Honda fluid for transmission, but from what I have read Honda made some significant changes in their fluid since 2011. Works for me and I never have a problem. Just my inputs though.
You're hilarious - beeswax? You should go to bobistheoilguy.com to get up to speed on modern day oils - thousands of members with lots of oil knowledge over there. Conventional Pennzoil and the Pennzoil synthetics are some of the most recommended.#1 - if it works for you keep doing it.

The main thing is to simply have oil. I grew up with Mopars and Chevy's that all bled so I have been in the habit of checking when I fill up because - well - what else do you do while filling up? Polish my windows with Rain-X and check the oil.
I only hesitate at Pennzoil. Back in the day of dinosour oil the sludge build-up could be pretty significant. Like black vasoline coated nasty.
Does Pennzoil still use beeswax or is that a wive's tale? I still avoid it while wearing onions on my belt and compalining about the scary looking teenagers and commies.
Yeah, I think I'm gonna switch back to platinum after using Mobil 1 AFE for the last few changes. I change mine out at 15% on the maintenance minder which is at about 5000 miles for me (lots of stop and go). Your motor is gonna be very clean and last a very long time at your change interval, especially if you're using ultra.Pennzoil has changed a lot in the past 15 years. Yes, their oil use to be horrible, but as it stands now Pennzoil is the top rated synthetic, above Mobil 1 and other competitors. Yes I know I can go longer than 3,000 miles on my oil changes, but I have an unlimited supply so I might as well.
I have no idea about the past of US market, but i know that Pennzoil is owned by Shell, and Shell is one of the most popular oil brands in Europe.Pennzoil has changed a lot in the past 15 years.

Hey, I'm glad you woke up this discussion - I like hearing everyone's oil advice. I'm disappointed when there's no posts here for a long time.Wow, a little sarcasm and this thread is back off and running. I've been a Mobil 1 guy for 300k on my 8th but switched to Rotella per Testify's recommendation.
I'm 46 and tearing apart engines at 18 made some impressions on me. Sorry but it sticks with you when something fails you.
The synthetics are the bomb to eliminate sludge. I don't run anything high performance so I haven't dwelved into the Amsoil or others.
/Off to ask Bob the Oil Guy if I should use Marvel Mystery Oil
//Happy Thanksgiving guys!
I've spent hours pouring over research and I must say......If an LX's oil changed is changed below 5k miles, then any name brand *conventional* oil will be fine. Probably easily go 8k+ on convention without issue. The delta between the off the shelf synthetics and most modern conventionals is getting exceedingly small these days.
BH- Do you change your own at home?I just use Mobil 1 Extended Performance for my cars and amsoil for my ATV/Waverunner, it's like $4 more (if that) for the Mobil 1 EP in a 5 quart container over cheap conventional/semi-syn at walmart.
I go to 5k or my OLM to 20%.
Satisfaction to my OCD of full synthetic
Cheaper than conventional at the dealer
and of course, confidence for :vtec:
