Which viscosity for me: Royal Purple 5w30 or 10w30?

Go with 10w30, it'll have less of a tendancy to thin out. My wife's car is running 5w30 RP right now, but on the next oil change I'm switching it to 10w30 RP.

After seeing all the nice UOAs with 30wts and even 20wts, this site has really educated me. I think Im finally bold enough to try it out myself. Seeing that toyota also recommends it, it cant be all that bad? It'll be quite an overcoming for me, I've always been a 20w50 man you see.  -

Thanks guys! I had a hunch 10w30 would be better for me. BTW Patman, I've got another one for you: 'You know you are obsessed with oil when....you start posting msgs at 5.18 in the morning!' [Cheers!]

Hehe, good one! (actually, I got up at 4:30 and started reading the board shortly after that) [Smile]

[Off Topic!] Ken4, Did you notice the typo in line 4 of the viscosity chart you showed us (inside the parentheses)? [LOL!] [ July 23, 2003, 01:37 PM: Message edited by: pscholte ]

Slightly [Off Topic!] , Ken4, what is the wording after the 5W-20 asterisk. Is it some warning about resticted use for this grade of oil in these temp ranges? It's interesting that both the 5W-30 and 5W-20 have the same temp range in the manual, of course with the asterisk for the 5W-20 recommendation. Thanks, Whimsey

My guess is: 'The Environment Ministry has declared 5w20 a superb oil for fuel economy.' But I think I still prefer your definition, pscholte! [Big Grin]
