Kupaka mafuta kumakhudza kwambirimphetemoyo wautumiki ndi kukangana, kuvala, kugwedezeka, ndi zina. Kupaka mafuta abwino ndikofunikira kuti zitsimikizidwe kuti zikuyenda bwino.mphete.Malinga ndi ziwerengero, pafupifupi 40% yakuphakuwonongeka kumakhudzana ndi mafuta osakwanira.

Waukulu zotsatira za kondomu pamphetezikuphatikizapo:

1) Pewani dzimbiri zachitsulo

2) Pewani kulowerera kwa zinthu zakunja ndikuchita ntchito yosindikiza

3) Chotsani kutentha kwamphamvu kuti muteteze kutentha kwakukulu kwa kutenthamphete

4) Chepetsani kukangana ndi kuvala ndikuwonjezera moyo wamphete

Kuphatikiza apo, ngati mafutawo sasinthidwa munthawi yake, angayambitsenso kuwonongekamphete.

Monga gawo lofunikira,kuphas amagwiritsidwa ntchito mu makina osiyanasiyana akuluakulu ndi ang'onoang'ono.Makina ena (monga ophwanya) amakhala ndi fumbi lambiri pamalo ogwirira ntchito.Pamene gawo la fumbi labwino limalowa m'liwiro lalikulukuphapampando, mafuta opaka m'malo mwakekuphampando kapena mafuta amawonongeka ndipo mafutawo sakhala bwino, zomwe zimayambitsamphetekuvala.

Slewing kuberekasnthawi zambiri amakhala No. 2 lithiamu mafuta kapena ofanana.Msewu wakuphaAyenera kupakidwa mafuta pafupipafupi, koma kuchuluka kwa nthawi yopaka mafuta kumasiyana malinga ndi momwe akugwiritsira ntchito komanso chilengedwe.Mwambiri,Xuzhou wanda slewing bear kampani ikusonyeza inu monga pansipa:Bzokopa zonseayenera kuthiridwa mafuta maola 100 aliwonse;
