난이도 & 준비물
증상
5.3 Triton 3V 엔진이 수동에서 5W-20을 지정하고 있으나, 매우 더운 기후(최저 20°C, 최고 45°C)에서 5W-30, 10W-30 또는 5W-40으로 변경할 수 있는지 궁금함. 엔진이 250,000km 주행함.
처리 내용
일반적으로 제조사 지정 오일 등급을 변경하지 마십시오. 이는 VVT(Variable Valve Timing)와 관련이 있습니다. 더 높은 점도의 오일로 변경하면 VVT 시스템에 문제가 발생할 수 있습니다. 엔진을 제대로 유지관리했다면 5W-20을 계속 사용해도 전혀 문제가 없습니다. 더 높은 점도 오일의 또 다른 문제는 유동성이 낮다는 것입니다. 베어링이 더 낮은 점도 오일을 기준으로 설계되었으므로, 더 높은 점도 오일을 사용하면 베어링에 필요한 오일 공급이 부족할 수 있습니다. 이렇게 하면 엔진에 손상을 줄 수 있습니다. 주의: 소유자 설명서(또는 온라인에서 찾은 것)를 확인하세요. 더운 조건에서 더 높은 점도 오일 사용을 명시하고 있을 수 있습니다. 명시되어 있다면 그대로 따르세요.

All due respect to the current Puma, which is a decent car that drives well, but there is only one in my eyes.I had a Mk1 Puma 1.7 in Moondust Silver when I was 21 as my daily car. I loved how it drove and went everywhere in it, and the car was sort of part of the reason my partner & I got together. I ended up selling it to move on to something else, as we usually do at that fickle age, but I've always hankered after another.I've viewed many Puma's that have promised to be amazing, only to be let down by predictable corrosion (a notable one being a 9k mile example a few years ago that had a fi

Collected this yesterday. I had been waiting for the right spec car since Christmas. I wanted; Clubsport pack, PDK, dual zone climate, either shark or gentian blue, yellow sticking, leather dash, sports chrono, rear camera, FPSH and Porsche warranty. Everything that came up matching that was either over budget, sold before it was advertised or sold the day it was advertised. I even lost out on a car to Jay Kay, cool story, bro. I left my details and requirements with the likes of RPM and JZM in the hope of a call before a car was advertised. There was some time pressure. I naively booked a tra
