Yesterday I contacted Havoline tech support about Lifelong oil and asked about seal conditioners. Here is the response: "lifelong is a full synthetic and designed to work for new vehicles, and older or high mileage vehicles. It does not contain seal conditioners." I replied showing that Walmart...

I am also planning to send Acura full synthetic 5w-20 for testing when I get a chance. Just trying to pick an oil and stick to it.

I got a report from the lab for virgin 5w-20 Acura synthetic blend oil and it seems to be good. Anyone?

The reason I asked is that I am using Pennzoil Ultra 5w-20 and it has 8.8 at 100 degrees and the Platinum's cSt is at 8.6 per same degrees. I wonder what Acura's oil has in it and why would it be a bit thinner.

Does anyone think the below Acura Full Synthetic of 5w-20 seems too thin having a cSt of 8.2 at 100 degrees C? https://shop.sclubricants.com/automotive/motor-oil/pcmo/acura-fs-5w-20

Hey guys, some update: I changed oil on Monday and this time used Pennzoil Ultra Platinum instead of Platinum. Engine sound didn't change even though, this time I was used Honda oil filter and not Purolator One. I thought the noise in the engine could be a filter issue, but looks like it could...

I would have changed the filter after I started the thread, but I live in the apartments where they no longer allow tenants to work on their cars(for many years now). So I go to the place where I book a time with a lift and for 30 min oil change it is $20... I agree with you on changing one...

I see. For comparison Acura's synthetic blend has 47 at Kinematic Viscosity cSt 40°C according to specs(link below) and Kinematic Viscosity cSt 100°C is 8.5. The PUP has 48 and 8.8 and Pennzoil has a deal of $22 shell card with purchase of 2 5QT jags, so I might as well get the Ultra Platinum...

After I switched to full synthetic, I decided to do shorter OCI and didn't reset the system. At that time oil life was at 50%. I hardly drove over 900 miles and now oil life is at 30% and has been like this for 3 weeks. I am expecting maintenance minder to let me know soon.

Does anyone understand this: Kinematic Viscosity cSt 40°C for 5w-20 Pennzoil Platinum is 45.9 and for Pennzoil Ultra is 48. Which number is better and what does it mean?

Great as I would only have to listed to the radio for a few first minutes after starting the car :)

Anyone that understands oil, please tell me: 1) Is synthetic blend oil having: - Kinematic Viscosity cSt 40°C being a 47.0 is better than Pennzoil Platinum of 45.9? 2) For the synthetic blend oil: Kinematic Viscosity cSt 100°C being 8.5 is better than Pennzoil Platinum is at 8.6? Which numbers...

Looks like I found some info(specs) on synthetic blend 5w-20 "Acura oil": https://shop.sclubricants.com/acura-sb-5w-20 Looks like the blend shows Kinematic Viscosity cSt 40°C at 47.0, then Pennzoil Platinum at 45.9 And the Kinematic Viscosity cSt 100°C, the blend is 8.5 and Pennzoil Platinum is...

Good idea. Since I don't really know how factory/non-factory RTV should look like, I will try to take a video. I have watched few videos of J series valve adjustment videos, but they didn't specify if it was 3.5 or 3.7, but this seems to be an involved job. Adjusting valves probably isn't that...

I haven't, but 12k miles ago original owner did 105k service a bit early(was done at around 101k miles) at Acura dealership and they did timing belt, tensioner and water pump. Spark plugs should of been done as well. I believe at that time, techs could of adjusted valves if they needed...

Is this in 5w-20 or 5w-30?

Interesting post to look at :) You engine seems to be good and practically clean! Below is the image before I poured PP in and original owner did 7k oil changes as MID was telling him

Happy to hear that, just imagine a bit lower noise of the valves with synthetic blend oil. 1) What oil(brand) are you running on your J-series engines? 2) What do you think about me trying PUP oil out next time?

Here is the warm engine sound: https://photos.app.goo.gl/fBkZwBWEHwM1uauK6 Here is the cold inside the car. You may notice no knock at the start but after short time, it starts for 1 min or so, then goes away: https://photos.app.goo.gl/qWL6wzkx7CbFr2Pk7 Also on this video at around 1:23, the...

I agree with you here and with Acura's blend oil, I would have changed oil every 2.5/3k miles which is half way of the maintenance system. On other hand with full synthetic I thought of extending to 5k as this would be inline with my car's maintenance minder system. If I won't be safely able to...
