Recently, I have been noticing significant oil loss from my b18b1 engine in my 1995 Acura Integra. I checked the dip stick one day and it was bone dry. I go under the car and saw that the 5w-30 fully synthetic oil I was using had leaked out of the oil pan and burned off on the exhaust. It was recommended to apply sealant on both sides of the new oil pan gasket and then apply a blend of conventional and synthetic oil to keep it from seeping out of the seal. I would gladly appreciate any suggestions. Thanks 🙂

5W-30? I thought the recommended oil for your car is 10W-30.
Personally, I wouldn’t go through the nonsense of using gasket sealer and blending oil. A new OEM pan gasket, clean (and undamaged) mating surfaces and proper bolt torque gradually applied in a criss-cross pattern over two or three progressive stages should make things oil-tight. Rocket science it ain’t.
Actually, I don’t know if you can blame your entire oil loss on the pan gasket alone. The normal oil level is some distance below the gasket surface. Maybe there’s an oil leak somewhere else and flowing downwards, making the pan gasket look like a suspect, or maybe your 21 year old engine is consuming some oil.
Nope, 5W-30. Says so in the manual. I don’t think using sealant on both sides of the gasket would do any harm would it? I rebuilt this engine over a year ago and it has held up pretty well, except for the leak. The valve cover is fine, so I know it’s not that. I have checked everywhere and haven’t seen any sign of leaks other than the oil pan, in a few areas. When I look on the exhaust, it had a oil streak starting from the front of the engine, right under where the oil pan is. No streaks going down that side of the engine, so I can suspect the oil pan.
Depending on how the gasket is to be installed by the MFG.
Some require sealant to be applied, some do not.
As stated the prep work is most important.
Also helps, if it is a flat gasket design, place the gasket between two flat surfaces to remove any twists.
One other item, check and see if the oil pan bolts require any type of sealant or thread retainer.
