subarunewb Posted April 3, 2015 Share Posted April 3, 2015 Purchased a 1995 Subaru Legacy L few weeks ago, and doing the first oil change here in a few days, because its due for a oil change. Mileage on my Legacy is 185,464. Oil change due at 185,600. Guy who had the car before used 5w-30. I've been looking around on the internet, and some websites say to use 10W-30. Which oil should I use? Link to comment Share on other sites More sharing options...
98legwag Posted April 3, 2015 Share Posted April 3, 2015 I have always used 5w-30 and have had no problems. Link to comment Share on other sites More sharing options...
Tr00b Posted April 3, 2015 Share Posted April 3, 2015 I have run 15w-40 for several years now due to perceived bottom end noise. Now I'm running 1qt Synthetic Lucas Stabilizer and 3 qt 10-30 Rotella T5. You want to protect the engine to some measure, you don't want it to start burning oil/making bottom end noise like mine. If mine WASN'T a flaming heap of hot oil guzzling garbage, I'd run 5-40 Rotella T6 like alot of the WRX guys. Link to comment Share on other sites More sharing options...
twisty Posted April 3, 2015 Share Posted April 3, 2015 i run 10w-40 in the summer here in az. when i get the ej25 rebuild finished it will likely run 5w-30 synthetic for the remainder of its life. Link to comment Share on other sites More sharing options...

johnegg Posted April 4, 2015 Share Posted April 4, 2015 5w-30 is for slightly colder climates. 10w-30 is for slightly warmer climates. here in va it does not matter. unless you have oil leaks, then thicker is better. Link to comment Share on other sites More sharing options...
stevenva Posted April 5, 2015 Share Posted April 5, 2015 5W-30. Look at my odometer in the picture. That was taken over 2 years ago. I'm now at 330,000 miles. RIP 96 Legacy 2.2 4EAT lost reverse @ 374,000 miles Link to comment Share on other sites More sharing options...

I'm at 185,569 right now. I need to do oil change at 185,795. I purchased some Penzoil 5w-30 at Walmart few days ago. Link to comment Share on other sites More sharing options...
SoSubiZ Posted April 6, 2015 Share Posted April 6, 2015 my last oil change 2qts of 5w20 castrol synblend 1+someqt of 10w40 castrol high mileage and 1 of 5w30 castrol edge. whatever I had laying around the garage. If its clean the car is happy. I assume. my question is does 1qt of 5w20+1qt of 10w40= 2qts of 7.5w30??? Link to comment Share on other sites More sharing options...

Correct, I'd switch by seasons....it'll be more important if car isn't garage kept. Link to comment Share on other sites More sharing options...
brokentv Posted April 9, 2015 Share Posted April 9, 2015 I use 5w-30 and have stuck with Pennzoil which has worked great for me. I dont know if I was just hearing things but I used another brand once and the engine sounded more clanky. Link to comment Share on other sites More sharing options...
johnegg Posted April 9, 2015 Share Posted April 9, 2015 discussing which oil weights to use is an ok topic . and a needed one if you do not have an owners manual. there is a great chart in the owners manual for which weights when. but lets leave oil brand out of it. it is a topic that can never be resolved . every one has a favorite and a worst. and if the discussion goes long enough some one may end up yelling and crying, "MOM, billy's picking on me." so lets agree, new oil, any new oil, is better than old dirty oil.
