Hello, i have been searching a good oil and filter for -92 L98 engine, i would like to keep using the same oil as the previous owner did, synthetic blend 5w30, but of course im open for recommendations, whether if the oil should be 10w30 or thicker, and if i should keep using the blend, or go full synth.
I just don't want to risk the chance of leaks, that's why i feel if im better off just keep using the blend, at least for now.
When i did an oil change a while back, all i could find really quick was shell helix oil, 10w40, i believe its a blend, (hx7), and since its winter, and im in EU, i poured one quart of shell helix ultra 5w40 full synth, just as a extra measure, to help protect the engine during cold starts since full synthetic flows better, supposedly.
For filter i used a Wix oil filter. But for my next oil chance, i feel like i want to go back to 5w30 weight, since the car has relatively low miles, uses no oil, so far, and the oil pressure is the same, tho with the 40 weight oil, it takes longer for the oil pressure to drop down to around 30 PSI at idle when the engine is warm, and i nodest that there's a cold start up rattle just a second or two, so perhaps the 30 weight oil would be more suitable for the engine, alltho could the oil filter be the cause of the rattle, do black wix filters have an anti drain back valve?
And also, if longer oil filter would be better to use than the short one, im thinking to do an oil change once a year since i don't drive thousands of miles a year.
Anyway, i would much appreciate recommendation of the appropriate oil weight, brand, specially a good blend brand, and recommendation oil filter wise, with part number, specially if its better to use the longer oil filters, since parts lookup pages usually just shows the part number for short filters, and i have no experience with the taller oil filters. It should be a oil filter with an antidrain back valve?
Some pages shows filters with and without the valve, and i dont know whether i should pick one with or without the anti drainback valve, what about the bypass valve, or is it irrelevant since if the L98 engines have the bypass valve on the thing where the oil filter is mounted on?
I don't want to step on anyone's toes, but if i may, i would like to stay away from e-core oil filters, tho they according to Google, have improved over time, and i like acdelco filters, just not the e-core, because i personally wouldn't feel at ease using a e-core oil filter, and not knowing if the filter is a improved one or not, and whether if its going to function well or not, and the white K&N filters with the welded nut,
i would like to stay away from those also, because i have read stories online, about some of them starting to leak over time, from the welded nut.
Also if i may, i would like to ask oil recommendation as what dexron oil is suitable for th700 transmission these days, in my time, it was dexron2, is it dexron6 these days? and is it full synthetic these days, or should i just try to find dexron3? Probably AcDelco transmission dexron oil is a safe bet?
Thanks in advance.
