7 exactly , with new filter .
Hey chem_man I'm confused. Are you referring to a Bravada or another model of Oldsmobile?What oil filter are you using? I know when I use the factory specified oil filter (or aftermarket) with our Oldsmobile, it takes 4.5 quarts. When I use an alternate filter (a little longer) it takes 5 quarts to hit the full mark. Just as an FYI, the factory specified filter is an ACDelco PF-47, and the larger one is a PF-52.
On the TraillBlazer I use the factory specified or aftermarket equivalent filter (Purolator PL25288).
Gotcha, thanks!kanaikis619, sorry for the confusion. I was referring to our 1992 Olds 88, not a cousin Bravada.
Same here 04 Envoy/original engine dipstick.In the couple of years I've had my 05TB 4.2 EXT., I think I've changed the oil at least 4 times and it always needs that extra little bit to get it full.
This might be a dipstick anomaly --- I wonder and don't know what to think so far.
The rubber grip on those Fram filters has been a blessing on numerous vehicles of mine over the years. That is the only reason I prefer them over others.There are so many good filters on the market today it's not funny. ACDelco filters are generally held in high regard, Among some of the other well thought of "premium filters" are Wix, Baldwin, Donaldson, the PurolatorONE and PurolatorBOSS filters, NAPA Gold and Platinum filters (made by Wix) and the Fram Tough Guard and the Fram Ultra.
Some people did not like that the Fram Extra Guard filter used a cardboard looking composite material ass the ends on the filtration media as compared to other brands such as Purolator using metal ends on their standard oil filter. Others did not like paying more money for the low end Fram filter when the similar Purolator had better filtration specifications, cost less, and used metal end
Me, well, I confess, I have used various Purolator filters for the last 20+ years and have transitioned away from the "low end" white (now red) Purolator filter to the PurolatorONE and PurolatorBOSS filters. Also, I do like the Wix/NAPA filters. We just purchased a 2022 Silverado with the 5.3L V8 engine and the first filters I have purchased for it are the Wix Extreme oil filters. Why? Because I could get the top of the line Wix oil filter from Rockauto.com for less money than I could get the NAPA Gold or Platinum filters or the PurolatorONE or PurolatorBOSS filters.
Regarding how often to change an oil filter, I always change the filter each time I change the oil. I would only reuse am oil filter if I did not have an extra filter on hand (say the new filter was defective and it was my last one). I always thought of it as why add dirty oil to clean oil when the cost of an oil filter is trivial to the cost of an engine.
