I got a bottle of store branded HDEO from Repco(a local parts shop in Australia). The label on it says "Manufactured for Repco Limited by Mobil Oil Australia Pty Ltd.", and it is rated API CI-4 and SL. However, it only mentions ACEA A2/B2, without other ACEA ratings. I thought passing CI-4 would...

Delvac MX in Oz has a TBN of 10, not sure if it's the same thing in other asian countries / sth america. http://www.mobil.com/Australia-English/Lubes/PDS/GLXXENCVLMOMobilDelvacMX15W-40.asp

No matter how the performance of it is, it's a rip off for $2.87 per quart.

Use TCW-3 2-stroke oil, at least they are ashless when burnt. Or you may wanna use some proper OCL.

I'm only a rookie, but in my opinion: sludge build up in one oci = amount of oil broken down - amount of sludge particles dispersant and cleansing agent handled. So base on the equation, a syn. oil will absolutely reduce the amount of oil breakdown, thus the dispersant/cleaners may be able to...

In Oz here, the Pennzoil 4WD dino is a SJ(SL?)/CH-4 rated oil, so probably Pennzoil is doing the same thing like mobil with their Delac-1 and M1 SUV. Not sure if that's the same thing as its counterparts in the US.

Got 2 quart of Delo 400 15W40 left after last oil change, since we're approaching winter down under, I'm thinking of adding another 2 liter of Havoline 5W40 syn. (probably group 3) to mix with the delo, do u guys have any comments on this mix?

The oil will be used in a GM 3800 series 1 V6, which oil is a better choice? Delvac MX or Delvac 1300? Both of them are API SL/CI-4, however, MX has a lower TBN while 1300 has a higher viscosity in cold and hot. What exactly are the differences between these 2 oil? They seem to be at a simular...

I reckon the Helix dino is not really that bad despite of the price. At least it have got a TBN of 8 instead of the 6.3 in Castrol GTX2 and 5 in BP Visco 2000.

That is just a ordinary low-end to mid-range sorta dino oil, nothing more, nothing less. It won't blow up ur engine but it's not superior than others in the same price level either. I reckon Shell Helix Super (yellow bottle) is a better buy, at least they met the ACEA A2/B2.

I reckon some of those volatile components might get evaporated at room temperature for prolonged period of time, may be that would cause a drop in amount of VI in dino oil. Maybe this will make the the oil a bit thicker and less cold flow ability. With less VI / more stable VI in synthetic's...

I used the BP3000 in my previous car prior selling it, seems to be good stuff, engine felt smoother and quieter compared to Castrol GTX. Also, besides the gasket leak, not much oil was lost during the service, should be pretty good. I now run Shell Helix City + Shell Helix Ultra (in 4:1 ratio)...

It was recommended by my transmission specialist when I got my auto transmission serviced there, any idea on whether it's good or not? Seems like he rate this at the same level of Lubegard. That additive is made by Life Automotive. http://www.lifeautomotive.com/Products/ATFP4001.asp

I recently found this product in a nearby autoparts shop, and I've got a bit lifter noise in my car. I wasn't able to find AutoRX in my place, so what do u guys think about this stuff by its formulation? How is it compared to ARX and how long should I let it stay in the motor? INGREDIENTS...
