Oil dipstick and tube
#24
NECRO!!!!
But, I'm currently struggling with this so I'm going the post the data I've found so far for posterity.
In my case, I just bought a 1995. The oil dipstick handle was, of course, broken. But in fine TX style, the handle had been replaced with epoxy and a 9mm shell casing. I'm not into that, so I purchased the correct dipstick for a 1995 1.8 -- part number BPE8-10-450.
Now, the engine in this car had been rebuilt about 3K miles ago with the PO complaining of excessive oil consumption. The engine is a 1995 block (has oil ports on driver's side) with 1999 head and IM (VICS). I "ASSUMED" that the 1995 block retained its dipstick tube and dipstick. But when I match up the new dipstick to the old, the new one is longer. "F" on the new one lines up with "E" on the old one. If the tube is the 1995 version, that means the PO ran severely overfilled. Could this be the reason for the oil consumption?
These are the part numbers from the Mazda part books:
Oil Dipsticks:
90-93: B61P-10-450C (Tube is B61P-10-440) (DIP STICK (B61P-10-450C) - $10.92 - B61P10450C)
94-97: BPE8-10-450 (Tube is BPE8-10-440) (DIP STICK (BPE8-10-450) - $18.24 - BPE810450)
99-05: BP4W-10-450 (Tube is BP4W-10-440A) (DIP STICK (BP4W-10-450) - $19.99 - BP4W10450)
Oil Pans:
90-93 (1.6)
94-00 (1.8 w/o MBSP)
01-05 (1.8 w/ MBSP)
So . . . anyone know how to visually identify the difference between the 94-97 vs. 99-05 tubes?
Incidentally, the 94-97 dipstick ("BPE8" on handle) is nearly a perfect match to the 90-93 dipstick ("B61P" on handle) on my 90. You could safely swap those in a pinch.

The one from my '96 is longer than the one reading BP4W. Therefore the one for the BP4W requires more oil in the pan to read full. Yes, the full mark of the longer one is even with the low mark of the other.

Since the 1.8 used the same oil pan until the '01 MBSP pans, I'm almost sure that the late 1.8 disptick tubes would need to be shorter to match the dipstick. My wild guess is that this might have been an "attempt" to keep the handles from breaking so often.

Just stumbled on this for the first time today... Im kind of concerned. I have a bp4w with an NA8 oil pan, and a NA6 dipstick tube and dipstick. Im not sure whether that would read high or low at this point...
Anyone have some insight? It always seemed to read high, but with the NA8 pan im not so sure what to think.

Fabulous, I just noticed last night the pan on the spare engine I picked is a BPE8 but it has the "California" braided wire dipstick. No clue on the tube, and its a mutt for parts
Any chance we can use this thread to start confirming and consolidating this info? Confirm the tube and stick PNs and measure the lengths? It would be nice to know what exactly is interchangeable.

I drain and dump 4 quarts and monitor level from there.
I do actually have a bunch of dipsticks from various motors in the shop right now. I have a 1.6, a BP4W, and several BP6D sticks and tubes. Maybe if I'm feeling benevolent I'll measure a few of them this week.

Just order cases of the stuff when its on sale on Amazon (since I refuse to Walmart). The correct answer is Rotella T6.

My NA6 dipstick is different to the BP4W dipstick.
If i'm ok with the NA6 dipstifck in the BP4W
I'm totally overfilled with the BP4W dipostick in the BP4W.
1.6 is definitely different to the 1.8
they both fasten at the same spot on the gearbox metal thingy
dipsticks are different lenths.
Full reference points are in different positions.
