OutdoorKing Repair Forum Forums Repairs and Maintenance Questions on Engines Questions On Briggs & Stratton Engines Using Old 20/20w Oil in Briggs.

I think I have used Vantage - almost got some at repco last month when it was out cheap but got more ultraclean at SCA instead.

I have got a variety of different oils here - 20w50 GTX, 10w40 magnatec, 15w40 gulf western, 15w40 Nulon, 10w30 Valvoline, 15w40 castrol ultraclean, dregs 15w40 gtx modern engine, penrite sae30, B&S sae30, magnatec 10w30 and another one somewhere I can't remember what it is

I change oil regularly and restock when on special - think there are somewhere around 6 bottles of ultraclean around here - $44 regular price but have never paid more than $22 for a bottle.

The Nulon and G Western are for flushing once or twice before the good stuff goes in

Wow you're very conscientious and savvy with the bargains.
How often do you change car engine oil filters? Are you one who will change them every time regardless how much distance was covered?
Do you go for most expensive filter or cheapest?
With my Laser 1.6 I change filter every second time because I discovered all the old dirty oil will actually drain out and there will be non trapped behind the filter and I don't reach anywhere near the recommended oil change distance, whereas with the 302 V8 more oil drains out as you loosen the filter. after the sump is done draining.

I usually change filters every second oil change - usually somewhere between 2 and 4 oil changes per year depending on km. Eg, have done 10,000 km this year in my Tuscon, and have changed it 3 times and will change once more shortly (seems to have some gunk in there)

Meanwhile, the Camira does maybe 800 km between 6 month oil changes, with the filter done at the same time due to being an old engine and presumably worn rings

I use standard ryco filters (again, I try to get them on special), but have used valvoline as well.
