Yes. Most owners have done at least one oil change since 1990! The odds of a factory installed filter is nil. Besides, AC DELCO didn?t make one kind just for the factory and one for the general public or replacement inventory.

Well I have seen them in black with the filter label in the upright position when installed as opposed to the ones shown here., this is why I brought this up.

At the risk of beating a dead horse?
One thing for sure, I know less than everybody on this site so, I am just trying to learn. I was under the impression this label was used in Model Year (MY) 1990 ZR1 applications. Although a new NCRS TIM&JG is forthcoming, the current version says this label was used in MY 1990, and may say 1991 as well. I do not have the manual in front of me? ![]() As for two versions being used in the same MY, are you sure that was not the case in MY 1990 and others? The reason I ask, there is strong evidence to show there were visual differences in MY 1969 & 1970 between assembly line and service filters. Assembly line filters were white with black silkscreening. Service filters were white with red & blue silkscreening. Originals have been noted across model lines, Corvette, Camaro, Nova, etc. Again, my ignorance with regard to our ZR1s is showing. I judge 68/69 at BG and NCRS and am, at least a little, more knowledgable with those years. Last edited by AirbusDriver; 07-03-2021 at 02:17 PM. |

Pre-production LT5 had the label readable (bottom photo) and so was the first production LT5 engine (top photo).

Thanks I know the black filter with black & white label were used from the factory.
My ? is about the ones with the label oriented upside down when installed as shown by lfalzarano in post 2 of this thread. Did they come from the factory with this filter or was it a mistake on a run of over the counter filters?

The filter in Lou's post is a service replacement. Note it says "Duraguard" on the label which is not correct for 1990 NCRS judging without a point deduction.

Several years I bought some of the oil filter labels & they would not stay stuck to the filter. As the oil heated up they would start to curl up & come off. I always spray the filters semi gloss Black so they at least look original.
