Using old API SH oil in my 02' Nissan.

[55Test]

Your '02 Nissan calls for SH rated oil? Man that mofo is really out of date. Check with your dealer and see if they have updated info. The SH rating has got to be 8-10 year old at least.


edit: noticed it said SH, not SG.

Pennzoil PZL Turbo SH was one of the best conventional oils available in its day (circa 1994). I would imagine that any SL rated conventional oil would be as good or better. I don't think you would harm anything using it for 3 or 4k OCI this time of year.

The 2005 Hyundai motors are SH/GF-1 or higher oil also.

Looks like a case for oil mixing is at hand.

The Chilton book for my 99 Chev truck shows SG as the current recommendation, just for comparison..

If you have the oil, and if it is the weight that you use, Then I wouldn't see a problem using it....especially with 3-4k OCI.

It may burn off a little (probably not noticeably) more than current SL/SM oil possibly, may have a little higher zinc, but if I had it out in the garage, I'd be using it in my truck(s)...89Nissan/95Chev/99Chev.

I've got some SJ marine Pennzoil 15w40 out there now that I got for $.25 ea, that I have been using in the Nissan, and mixing with 10w30 in the Chevs.

If its the purebase API SH oil, use it without issue. Otherwise, Id use it at a reduced OCI. My biggest issue would be shelf life.

I have a few cases of 10w30 Pennzoil PZL Turbo oil I've had for who knows how long. Its API SH, energy conserving II. The owners manual for my car was much out of date when written and allows for use of a API SG and 10W40. From the back of the bottle: PZL Turbo is specially designed to protect against high temputure deposits that can be created in turbocharged engines. Formulated with Pennzoils unique Z-7 additive (oh boy, zinc like every other oil?) and our revolutionary Pennzstar molecule. Does anyone know of the makeup of this old oil? Would using a cheap Wal-mart supertech oil with the newest rating provide better protection? The Pennzoil is in the crankcase right now.

Why not adding in a quart per oil change with the rest being new fresh oil. This will minimize the effect of any aging issue yet let you finish it off.
