Hi all! Car has a oil pan leak. 98 Buick lesabre limited.got it Craigslist 2 years ago,had so many problems,I've since fixed. Had 111,000 miles or so,on it. Now 124,000. So!last year I put Castro synthetic in it,edge, 0w30. Wanted too try different. Leak developed from oil filter area.oil pan gasket,facing filter side.it's not a bad leak at all. Put a large red bottle of gumout oil stop leak I bought a while back!it wirked,mostly!still drips a little. Can,bars leak stop leak,for oil,he used,with synthetic oil? I have quarts,of Pennzoil ultra I bought on clearance autozone, 2013 stockpiled.I do know,it has a lot of calcium in it. That means,clean. I used mobil1 in a 95 neon some 15 years ago. It cleaned so well,my dear main had to be replaced on that car.but puddle of fresh oil under the car. So!with my lesabre, I know not too use synthetic.unless,it has stop leak in it,like high mileage have conditioners. Is it risky?ok? Too use the bars leak with Pennzoil ultra? Would the oil basically clean,the bars leak won't work?
