Just looking at the spec sheet, doesnt look too bad at all. Anyone use this? and where can you buy it? I currently use RT 10w-30 CJ-4 in the subaru in the mild weather - but I am always open to options. http://www.wd-wpp.com/specsheet/specshee004.pdf

Ok, so I just picked up 5 quarts of Penzoil Platinum. The lady at the store recommended me getting 10w-30 over 5w-30 because my engine has about 120k miles on it, is it better to get 10w-30 if my car has high mileage? Also, are Penzoil Platinum any good? Suggestions and Experience with using Penzoil would be nice. Thanks.

the oil cap says 5w-30 but in California I see 32 degree weather maybe 5 times a year and 100+ 40 days.Can I run 10w-30 without damaging anything, is there an advantage with 5w compared to 10w. I have 20k on 04 Sierra truck and 50k on 04 Yukon I am using castrol syntec in both.Thanks for any input.

Called Pennzoil and they mailed me the spec sheet for SuperTech 10W-30 synthetic. I asked for the sheet for the 5W-30 too and the rep looked but could not find it and his comment was, "Maybe we don't make that one." Seems to support the typical WalMart experience of frequent vendor/supplier changes. At least as of this writing, and since 3/30/05 according to the fine print on the spec sheet, the ...

Previously, I've been using 10W-20. Yesterday, I put in 10W-30. The car actually feels better and less noise. I have an old 1995 nissan. 1 - does this mean that 10W-30 is actually better? 2 - what do all the other "numbers" mean? ie 5W-10, 0W-10, etc.... Usually, the mech puts in the oil for me, but it was running fairly low yesterday, so I decided to buy the Castrol 10W-30 from ...

How good is this Mystik HD oil compared to Rotella? I am having a hard time getting anything but 15w-40 Rotella around here, but the local Theisens has Mystik HD semi synthetic for 19 bucks for 2 gallons.

Thanks for the HM reminder, I was talking conventional oil regularly about 3 buck a qt. I see the mc5HM is same weight as std mc5. My fav 10w-30 HM oil was redbottle QS by far (slick 50 appellation notwithstanding).

You must use motorcycle oils because they will not be broken down in the gearbox. Engine and gearbox share oil supply. 20w40 or 20w 50 might be a better choice
