Oil filter application for '91na
 

I'm finding that I get different oil filter application numbers depending on the source I look to for my '91na. Fram lists 6607 as the filter for 90-95 cars - but does an '89 S5 take a different filter than 90-91's? (and apparently they're unaware the FD was available later than 95 in Canada. Quaker State (really a Purolator - same for Valvoline) lists 3593 - same number as any 86-91, NA or turbo - and these brands all follow Fram's model numbers. Canuck Tire on the other hand lists 6607 regardless of brand - even tho' QS and Valvoline don't appear to offer it - just the 3593. I assume this is the correct one - but I hate to assume.
BTW, anyone know if the Valvoline High Mileage is actually different from the Quaker State version - and if so is it actually better? It seems to suggest more effective filtering media on the box - but this could also mean more restrictive.
Sorry for resurrecting the oil filter discussion in another guise - tried and search and didn't find my specific questions. :)

:eek: omg, another oil filter thread!!


anyways, to answer your question, no. in fact i believe that all FBs and FCs accept the same filter...even if there are different parts numbers, they should fit either generation and every year. not 100% sure though...
anyway, the 3593 will fit.

as for high mileage oil filters, i personally wouldn't use one...two reasons:
1) normal oil filters work fine
2) i'm not entirely sure what is described in the following statement is safe for our engines:
"FRAM[R] introduces the High Mileage[TM] Oil Filter, designed for vehicles with more than 75,000 miles. The oil filter features a time-released additive gel housed in a plastic basket that dissolves slowly into the oil. Because vehicles with higher mileage break down oil more rapidly, according to the company, the additive helps maintain viscosity, reduce corrosive engine wear and neutralize acids to keep the engine components cleaner."

but i'm sure you won't notice any difference either way...

GAAAAAAAAAAAHHHH!!!!!!!!! You guys are killing me.

Thx, Quaker State 3593 it is...
Cheers
