oil weight

[4play]

just wondering if switching to 5w30 woud hurt anything? I want to switch to a little heavier oil to see if that helps that idle knock... thinking maybe 520 is a little thin once the car warms up... in my case.

5w30 shouldn't hurt but i highly doubt it is gonna help quiet anything either

well I figure since it only does it when hot, maybe a thicker oil MIGHT do something, but if not i'll switch back.

Use the factory weight and use a bottle of Lucas oil stabilizer in the white jug, works great on my little tracer with 192K miles. Quite as a church mouse.

Using 5W-30 won't hurt a thing, but if you have a "knock" at idle, you have more major problems.

5w20, 5w30, 10w30, no problems.

5w20, 5w30, 10w30, no problems.

Its amazing how much oil pressure you gain in the hot summer temps with 10w-30.

I just recently bumped mine up at my last oil change actually! I went from 5w-20 to 5w-30. Just more peace of mind in the hot summer months!

thanks ima gana try 5w30 next oil change... serious problem knock nah, other members on here have the same knock im talking about, even someone with a blower has had it for 70,000 miles i think he said, nevr got worse. been to several Mechanics, not a berring knock, not a pisten knock... they dont know. as soon as you rev it to 800 rpms or more it's gone. also on a cold start up, nothing. so I was thinking maybe it has something to do with the oil once it thins out a bit?

[RF Overlord]

4play, do you have the stock non-functioning oil pressure gauge, or has it been replaced with a real working one? (You know the stock one is a fake, right?)

[4play]

I knew that within 5 min after purchasing the car. I keep meaning to get the pressure checked, but never had time. I cant see whatelse would cause the tap once it warms up. Whatelse changes becides the oil weight?... its worth a shot.

5w20, 5w30, 10w30, no problems.

The 10w30 will be fine in Tennessee, but do not use the 10w30 in the winter months in Canada. In the winter in Canada use the 5w20 or even the 5w30.

Does anyone know of any reasons why running any of the following oil weights would be a bad idea?

0w30 - this is the Castrol type-5 synthetic made in Germany;
5w50 - same cold start flow as a 5w20, but thicker than 5w20 or 5w30 once warmed up;
5w40 - I've seen this weight too, at my local FLAPS, a bit lighter than 5w50;

Sounds like the dreaded cylinder #4/#8 dead spot. Start saving some cash for a new motor some have just lived with it others were'nt so lucky
